The generally accepted method of purification of process streams for monoclonal antibodies includes capture of the product target with Protein A, elution, acidification to inactivate potential Mammalian viruses, followed by cation exchange chromatography, and finally anion exchange chromatography.

Protein purification is a series of processes intended to isolate a single type of protein from a complex mixture.

* Protein tag, describing addition of peptide sequences to enable protein isolation

While the infectious agent was named a prion, the specific protein that the prion was composed of is also known as the Prion Protein ( PrP ), though this protein may occur both in infectious and non-infectious forms.

Protein binding can be extraordinarily tight and specific ; for example, the ribonuclease inhibitor protein binds to human angiogenin with a sub-femtomolar dissociation constant (< 10 < sup >− 15 </ sup > M ) but does not bind at all to its amphibian homolog onconase (> 1 M ).

* Protein – a class of biochemicals made from amino acids in specific sequences.

* Iron Regulatory Protein are proteins that can bind to iron response elements and affect mRNA translation, thereby regulating the synthesis of specific proteins.

Protein kinases ( PKs ) are the effectors of phosphorylation and catalyse the transfer of a γ-phosphate from ATP to specific amino acids on proteins.

The process of osteocytogenesis is largely unknown, but the following molecules have been shown to play a crucial role in the production of healthy osteocytes, either in correct numbers or specific distributions: Matrix Metalloproteinases ( MMPs ), Dentin Matrix Protein 1 ( DMP-1 ), Osteoblast / Osteocyte factor 45 ( OF45 ), Klotho gene, TGF Beta inducile factor ( TIEG ), Lysophosphatidic acid ( LPA ), E11 antigen, and Oxygen.

Protein specific binding is required for the CCAAT box activation.

Protein tags find many other usages, such as specific enzymatic modification ( such as biotin ligase tags ) and chemical modification ( FlAsH ) tag.

** Protein electrophoresis, a specific type of gel electrophoresis used to analyse proteins

Protein A, protein G, and protein L are examples of proteins that strongly bind to various antibody isotypes.

Low carbohydrate diets such as Atkins and Protein Power are relatively high in protein and fats.

In the description of protein structure, in particular in the Protein Data Bank file format, a heteroatom record ( HETATM ) describes an atom as belonging to a small molecule cofactor rather than to be part of a biopolymer chain.

* Protein module or protein domain

Solved structures are usually deposited in the Protein Data Bank ( PDB ), a freely available resource from which structural data about thousands of proteins can be obtained in the form of Cartesian coordinates for each atom in the protein.

Protein – protein interactions also regulate enzymatic activity, control progression through the cell cycle, and allow the assembly of large protein complexes that carry out many closely related reactions with a common biological function.

Protein targeting or protein sorting is the mechanism by which a cell transports proteins to the appropriate positions in the cell or outside of it.

* Protein sequencer, a machine used to automatically produce a sequence readout from a biological protein sample

Once the model of a molecule's structure has been finalized, it is often deposited in a crystallographic database such as the Cambridge Structural Database ( for small molecules ), the Inorganic Crystal Structure Database ( ICSD ) ( for inorganic compounds ) or the Protein Data Bank ( for protein structures ).

Three-dimensional protein structures of the peroxidated catalase intermediates are available at the Protein Data Bank.

* Protein domain, a part of a protein that can exist independently of the rest of the protein chain

Protein kinases are a group of enzymes that possess a catalytic subunit that transfers the gamma ( terminal ) phosphate from nucleotide triphosphates ( often ATP ) to one or more amino acid residues in a protein substrate side chain, resulting in a conformational change affecting protein function.

Protein folding is the process by which a protein structure assumes its functional shape or conformation.

An example of a Green Fluorescent Protein | GFP fusion protein.

Protein methylation typically takes place on arginine or lysine amino acid residues in the protein sequence.

Protein sequence can be determined by Edman degradation, in which the N-terminal residues are hydrolyzed from the chain one at a time, derivatized, and then identified.

The images below are of Lipscomb's structures from the Protein Data Bank displayed in simplified form with atomic detail suppressed.

Protein thermal stability is far from constant, however.

Protein intake includes a wide range of delicacies, including lizards, insects, frogs, and wild deer that also come from the forests.

The Bioinformatics core of the Joint center for structural genomics ( JCSG ) has recently developed a wiki-based approach namely The Open Protein Structure Annotation Network ( TOPSAN ) for annotating protein structures emerging from high-throughput structural genomics centers.

Protein structure prediction is the prediction of the three-dimensional structure of a protein from its amino acid sequence — that is, the prediction of its secondary, tertiary, and quaternary structure from its primary structure.

Protein synthesis resumes as SRP is released from the ribosome.

* Protein, the NIH protein database, a collection of sequences from several sources, including translations from annotated coding regions in GenBank, RefSeq and TPA, as well as records from SwissProt, PIR, PRF, and PDB

In 2010, in close cooperation with the Nanomedicine Center for Protein Folding, these drug leads went from the test tube to testing on biological tissue.

Protein intake are mostly taken from beef, water buffalo, goat, and lamb meat, and also includes poultry and fishes.

HOP ( the Hsp70 / Hsp90 Organizing Protein ) can bind to both Hsp70 and Hsp90 at the same time, and mediates the transfer of peptides from Hsp70 to Hsp90.

Crystals were obtained from all the proteins in the Protein Crystal Growth experiment.

While many phage and viral SSBs function as monomers and eukaryotes encode heterotrimeric RPA ( Replication Protein A ), the best characterized SSB is that from the bacteria E. coli which, like most bacterial SSBs exists as a tetramer.
