Serine (symbol Ser or S) is an α-amino acid that is used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated −NH+...

Serine proteases (or serine endopeptidases) are enzymes that cleave peptide bonds in proteins. Serine serves as the nucleophilic amino acid at the (enzyme's)...

Serine dehydratase or L-serine ammonia lyase (SDH) is in the β-family of pyridoxal phosphate-dependent (PLP) enzymes. SDH is found widely in nature, but...

A serine/threonine protein kinase (EC 2.7.11.-) is a kinase enzyme, in particular a protein kinase, that phosphorylates the OH group of the amino-acid...

Serine hydroxymethyltransferase (SHMT) is a pyridoxal phosphate (PLP) (Vitamin B6) dependent enzyme (EC 2.1.2.1) which plays an important role in cellular...

enzymology, a serine-phosphoethanolamine synthase (EC 2.7.8.4) is an enzyme that catalyzes the chemical reaction CDP-ethanolamine + L-serine ⇌ {\displaystyle...

In enzymology, a serine O-acetyltransferase (EC 2.3.1.30) is an enzyme that catalyzes the chemical reaction acetyl-CoA + L-serine ⇌ {\displaystyle \rightleftharpoons...

Serine hydrolases are one of the largest known enzyme classes comprising approximately ~200 enzymes or 1% of the genes in the human proteome. A defining...

The enzyme L-serine ammonia-lyase (EC 4.3.1.17) catalyzes the chemical reaction L-serine = pyruvate + NH3 (overall reaction) (1a) L-serine = 2-aminoprop-2-enoate...

Serine racemase (SR, EC 5.1.1.18) is the first racemase enzyme in human biology to be identified. This enzyme converts L-serine to its enantiomer form...
