These modifications are often essential for the function or regulation of a protein ; for example, the carboxylation of glutamate allows for better binding of calcium cations, and the hydroxylation of proline is critical for maintaining connective tissues.

These preaching friars, with the authorization of Gregory IX, adopted ( with some modifications, e. g. the substitution of the " Gallican " for the " Roman " version of the Psalter ) the Breviary hitherto used exclusively by the Roman court, and with it gradually swept out of Europe all the earlier partial books ( Legendaries, Responsories ), & c., and to some extent the local Breviaries, like that of Sarum.

These practices, which matured in the Tang Dynasty, were to be inherited by the later dynasties with some modifications.

These modifications may also form a signal sequence which determines the final destination of the protein.

These successes allowed the government to concentrate in 1996 and 1997 on major structural reforms such as the implementation of a fully funded pension system ( partly modelled after Chile's pension system with major modifications ), reform of higher education, and the creation of a national treasury.

These modifications of the basic 8086 design were one of the first jobs assigned to Intel's then new design office and laboratory in Haifa, Israel.

These factors also make it quite common for modern-day builders to promote modifications to the basic design, such as adding a finger board, pedal, electronic pickup, drum head, or making the staff immovable.

These modifications include acetylation, methylation, ubiquitylation, phosphorylation and sumoylation.

These tournaments increasingly made various modifications to the College Bowl format, and came to be known as quiz bowl.

These cars are closer to standard form than in GT2, and in most cases modifications are restricted to those found in one-make cups.

These modifications make it easier to enter and exit the movement, and thus easier to incorporate into a long sequence of calls.

These changes include histone modifications, such as histone H3 methylation and histone H2A ubiquitination, as well as direct modification of the DNA itself, via the methylation of CpG sites.

These modifications also increase the stiffness and torsional rigidity of the chassis and have been adopted in Locosts in other countries.

These data include artifacts ( objects made or modified by humans ), features ( modifications to the site itself such as post molds, burials, and hearths ), ecofacts ( evidence for the local environment and resources being used such as snail shells, seeds, and butchered bones ).

These cars were built in five series and several modifications until 1996.

These rules have gone through a lot of modifications over the years.

These modifications stayed into use until the disintegration of the USSR on 25 December 1991, at which time the flag ceased to be a national flag.

These vibrations can be controlled by adding features like close-fitting spring guides or by aftermarket tuning done by " air-gunsmiths " who specialize in air gun modifications.

These sports are typically played using International Federation of Association Football ( FIFA ) rules, with modifications to the field of play, equipment, numbers of players, and other rules as required to make the game suitable for the athletes.

These changes are largely due to highly controlled modifications in gene expression.

These modifications include the shape of the listener's outer ear, the shape of the listener's head and body, the acoustical characteristics of the space in which the sound is played, and so on.

These modifications make Safari on Mac OS X and Windows look more similar to Safari on iPhone than previous versions.

These modifications were relatively simple and could be carried out by users who knew how to handle a soldering iron.

These PTIs provided useful data for subsequent engineering modifications.

These genes encode various nicotinic acetylcholine receptors.

These theories encompass the loss of information already retained in long term memory or the inability to encode new information again.

These leaves need not be explicit in computer memory — a null child pointer can encode the fact that this child is a leaf — but it simplifies some algorithms for operating on red – black trees if the leaves really are explicit nodes.

These are structural features that cannot be specified by connectivity alone and SMILES which encode this information are termed Isomeric SMILES.

These values don't account for the CPU time it takes to encode or decode the frames.

These goals are achieved partly by omitting some of Ada's more problematic features ( such as unrestricted parallel tasking ) and partly by introducing annotations or " formal comments " which encode the application designer's intentions and requirements for certain components of a program.

These theories are closely linked with the volley principle or volley theory, a mechanism by which groups of neurons can encode the timing of a sound waveform.

These out-of-range YCbCr values are used by xvYCC to encode colors outside the BT. 709 gamut.

These genes encode various transcription factors that trigger expression of other proteins.

These are constructions which encode intended causation on the part of the causer, but which do not encode any outcome: i. e., the speaker encodes and causer intentionality, but remains agnostic as to whether was felicitously effected.

These genes encode two parts of a transporter protein that is made primarily in the kidneys.

These mobile genetic elements may range from 10-200 kb and encode genes which contribute to the virulence of the respective pathogen.

These codes can encode a message into a number of symbols such that knowledge of any fraction of them allows one to recover the original message ( with high probability ).

These components come together around a central piece called a Brain, which houses a sensor and the necessary electronics to record, encode, decode, and otherwise control the recorded images.

These Sections form the basic categories of knowledge in the schema, and each one is given a special three-part numerical code to encode its place in the Outline's hierarchy.

These loops encode a hysteretic bistable switch in CDK1 activity relative to Cyclin B1 levels.

These genes encode the non-structural protein, including proteins necessary for replication of the viral genome, and are expressed before the genome is replicated.

These viruses encode one main proteinase and between one and three accessory proteinases which are mainly involved in expressing the replicase gene.

These RNAs are predicted to encode a large protein ( L: polymerase activity ), viral surface glycoproteins ( Gc and Gn ), and nonstructural NSM protein, as well as both nucleocapsid ( N ) and NSS proteins.
