However, the magnesium ion is not directly involved in the photosynthetic function and can be replaced by other divalent ions with little loss of activity.

However, x-ray crystallographic studies of both types of enzymes reveal that, other than containing a critical Mg2 + ion at the catalytic site, they are virtually unrelated to each other ; indeed template-dependent nucleotide polymerizing enzymes seem to have arisen independently twice during the early evolution of cells.

However, because the proton and the deuteron would be more than 200 times farther apart in the case of the electronic HDO molecule than in the case of the muonic ( p-μ-d )< sup >+</ sup > molecular ion, Jackson estimates that the rate of p-d " electron "- catalyzed fusion ( eCF ) is about 38 orders of magnitude ( 10 < sup > 38 </ sup >) slower than the rate of p-d muon-catalyzed fusion ( μCF ), which Jackson estimates to be about 10 < sup > 6 </ sup > per second, so p-d " electron "- catalyzed fusions ( eCF ) would be expected to occur at a rate of about 10 < sup >- 32 </ sup > per second, meaning that one p-d " electron "- catalyzed fusion ( eCF ) might occur once every 10 < sup > 24 </ sup > years or so .</ ref >

However, the unusual nature of ionic magnesium has also led to a major challenge in the use of the ion in biological systems.

However, the myosin head can hydrolyze ATP into adenosine diphosphate ( ADP ) and an inorganic phosphate ion.

However, in his paper he was wary of identifying the enzyme with the active ion movement, so he left out the term “ sodium-potassium pump ” from the title of his paper.

However, the first release candidate of Ion3 included a license change to a custom license based on the LGPL ( specifically modified versions must not use the name ion ).

However, depending on ion energy, sputtering of the reactor walls or the substrate may still occur.

However, Hall thrusters operate at the high specific impulses that is typical of electric propulsion.

However, under Jupiter's gravitational influence, this requires enlargement of the thrusters, which leads to an increase of the mobile suit is size and mass.

However, this innovative jurisprudence did not help the victims of the Bhopal Gas Tragedy who were unable to fully prosecute a class action litigation ( as understood in the American sense ) against Union Carbide due to procedural rules that would make such litigation impossible to conclude and unwieldy to carry out.

However, many Dachshunds are very tolerant and loyal to children within their family, but these children should be mindful of the vulnerability of the breed's back and not carry them around roughly.

However, in plant tissues that carry on photosynthesis, carotenoids act to quench electronically excited chlorophyll produced by visible light in a process called non-photochemical quenching, in order to prevent reactions which would otherwise infere with photosynthesis at high light levels.

However, others prefer to simply ignore flaming, noting that, in many cases, if the flamebait receives no attention, it will quickly be forgotten as forum discussions carry on.

However, it was well known that proteins are structural and functional macromolecules, some of which carry out enzymatic reactions of cells.

However, 42 States in the U. S. permit open carry of handguns, sometimes subject to licensing or location restrictions.

However, courts and various levels of government have indicated that the right is not without limit, and restrictions such as a prohibition of certain persons from owning or handling a gun ( convicted felons, mentally ill persons, persons under a restraining order ), a ban on certain types of ammunition ( armor-piercing, incendiary / tracer, explosive ), registration and restriction of certain types of firearms ( automatic weapons, short-barrelled shotguns, certain types of modifications ), and licensing requirements for possession or for public carry, have often passed judicial scrutiny ( although some of these points remain untested and others are currently under challenge ).

However, after doing some screen tests and storyboards, Toho figured Jet Jaguar would not be able to carry the film on his own, either in screen appearance or marketing value, so they shut the project down during pre-production.

However, they cannot own or carry one until the age of 18.

However, when defending, an underarm carry absorbed more shock and could be ' couched ' under the shoulder for maximum stability.

However, Hong Kong registered vehicles may apply for secondary mainland Chinese registration plates, and these can be driven across the border to mainland China ; likewise, left-hand drive cars seen in Hong Kong are usually primarily registered in mainland China and carry supplementary Hong Kong registration plates.

However, there is no evidence to suggest that a gay priest or lesbian priestess could not carry out this ritual for the sake of what it represents.

However, not all organisms that use light as a source of energy carry out photosynthesis, since photoheterotrophs use organic compounds, rather than carbon dioxide, as a source of carbon.

However, there are some types of bacteria that carry out anoxygenic photosynthesis, which consumes carbon dioxide but does not release oxygen.

However, he was able to overcome these power struggles and ultimately carry out his building projects.

However, in early 1490 the four cantons decided to carry out their duty to the Abbey and to invade the St. Gallen canton with an armed force.

However, Walt Disney knew that his plans for the land would be easier to carry out with more independence.

However, the conclusion is more precisely that in order for the prisoner to carry out his argument that the judge's sentence cannot be fulfilled, he must interpret the judge's announcement as ( B ).

However, some technologies cannot process or carry data fast enough for sufficiently high frame rates.

However, they cannot be used to carry currents in the radio frequency range or higher, which reverse direction millions to billions of times per second, because the energy tends to radiate off the cable as radio waves, causing power losses.
