Glutamine affects the regulatory system for E. coli glutamine synthetase
so as to promote the adenylylation of glutamine synthetase and inhibit
the deadenylylation. Why do these effects make good metabolic sense?
Phosphoribosyltransferase (PRT) catalyzes the attachment of a salvaged purine nitrogenous base on the activated form of ribose-5-phosphate called 5-phosphoribosyl-

- Galactose 1-phosphate: UDP-glucose uridyltransferase (GALT) is an enzyme important for the catabolism of galactose. Patients with GALT deficiency present within days of birth with feeding difficulty, fatigue, jaundice and liver problems, and failure to thrive. In addition, a buildup of galactose and its metabolites are present in the bloodstream. GALT catalyzes the following reaction in galactose catabolism. NOTE that GALT is reversible!!

It's an enzyme, and leucine is its substrate. It speeds up the rate at which leucine is converted to other substances. It's a small molecule, with a molecular weight around 50 mol If you were to write a chemical equation for certain biochemical reactions of leucine, leucine transaminase would appear on both sides.
