Inhibitors

Inhibitors Comment Organism Structure
pyruvate inhibited by an excess of substrate pyruvate; substrate inhibition, in excess, pyruvate enters in competition with the other substrate (glycine and/or NADH) preventing the site of reaction to take all the substrates to proceed with the enzymatic reaction. Its optimal concentration is determined to be round 2.0-2.3 mM Suberites domuncula
