previously believed to be synthesized by the CqsA enzyme.

Interestingly, SPSo cells do not appear to express DAT-1, and SPSo-mediated behavior is not rescued by exogenous DA ().
17 AADC is also known as 5HTP Decarboxylase or Dopa Decarboxylase (DDC); in animals, the enzyme generally has broad substrate specificity, catalyzing both serotonin and dopamine synthesis (reviewed by ).
18 Reporters to date have shown limited expression in identified dopaminergic and serotonergic neurons (; ), despite mutant phenotypes indicating function in those cells promoting serotonin and dopamine synthesis ().

So how can these factors have an effect on the rate of photosynthesis? Lets start off with the light intensity. When the light intensity is poor, there is a shortage of ATP and NADPH, as these are products from the light dependent reactions. Without these products the light independent reactions can't occur as glycerate 3-phosphate cannot be reduced. Therefore a shortage of these products will limit the rate of photosynthesis. When the carbon dioxide concentration is low, the amount of glycerate 3-phosphate produced is limited as carbon dioxide is needed for its production and therefore the rate of photosynthesis is affected. Finally, many enzymes are involved during the process of photosynthesis. At low temperatures these enzymes work slower. At high temperatures the enzymes no longer work effectively. This affects the rate of the reactions in the Calvin cycle and therefore the rate of photosynthesis will be affected.

In mammalian CNS, GABA is also synthesized from the polyamine putrescine via the enzymes diamine oxidase (DAO) and an aldehyde dehydrogenase (; ); such synthesis occurs in cells that do not express GAD.

This separation of cellular functions isnecessary because cyanobacteria have oxygen-evolving photosynthesis but the nitrogen-fixing enzyme, nitrogenase, is unstable inthe presence of oxygen.

N2 - Vibrio cholerae produces cholera autoinducer-1 (CAI-1), a signaling molecule previously believed to be synthesized by the CqsA enzyme. Here it is shown that CqsA does not directly synthesize CAI-1; instead, it synthesizes amino-CAI-1, which is then converted into CAI-1 in a CqsA-independent manner.

Multiple Choice Questions on Restriction enzymes ~ …

The enzyme is also regulated by covalent modification (adenylylation of a Tyrresidue), which results in an increase sensitivity to the cumulative feedbackinhibition by the above nine effectors. Adenylyltransferase is the enzyme whichcatalyzes both the adenylylation and deadenylylation of E. coli glutaminesynthetase, and this enzyme is complexed with a tetrameric regulatory protein, PII.Regulation of the adenylylation and its reverse occurs at the level of PII,depending upon the uridylylation of another Tyr residue, located on PII.When PII is uridylylated, glutamine synthetase is deadenylylated; thereverse occurs when UMP is covalently attached to the Tyr residue of PII.The level of uridylylation is, in turn, regulated by the activities of the twoenzymes, uridylyltransferase and uridylyl-removing enzyme, both located on thesame protein. Uridylyltransferase is activated by -ketoglutarateand ATP, while it is inhibited by glutamine and Pi.

Not just copies: Recent advances in supramolecular coordination chemistry have allowed chemists to synthesize macromolecular complexes that exhibit various properties intrinsic to enzymes. This Review focuses on structures inspired by properties and functions observed in enzymes rather than precise models of enzyme active sites. Many of the structures exhibit reactivity and specificity reminiscent of natural systems, and some of them have functions that exceed the natural systems which provided the inspiration for initially making them.
