Synthetase enzyme class
In biochemistry, a ligase is an enzyme that can catalyze the joining (ligation) of two large molecules by forming a new chemical bond. This is typically via hydrolysis of a small pendant chemical group on one of the larger molecules or the enzyme catalyzing the linking together of two compounds, e.g., enzymes that catalyze joining of C-O, C-S, C-N, etc. In general, a ligase catalyzes the following reaction: WebJul 28, 2024 · A second class of synthetase structure revealed by X-ray analysis of Escherichia coli seryl-tRNA synthetase at 2.5 A.

WebDec 30, 2024 · Acetyl-Coenzyme A is composed of four distinct molecular parts. 1. Once the pyruvate enters the mitochondrial matrix, the pyruvate dehydrogenase complex (consisting of three enzyme subunits E1, E2, and E3) converts it to acetyl-CoA (Figure 5.3. 3) for entry into the tricarboxylic acid cycle (TCA). This reaction generates NADH and liberates CO 2.
