A ubiquitin ligase (also called an E3 ubiquitin ligase) is a ligase enzyme that combines with a ubiquitin-containing E2 ubiquitin-conjugating enzyme recognizes the target protein that is to be ubiquinated […]

Choline acetyltransferase (commonly abbreviated as ChAT but sometimes CAT) is a transferase enzyme responsible for the synthesis of the neurotransmitter acetylcholine. ChAT catalyzes the transfer of an acetyl group from […]

Catechol-O-methyltransferase (COMT; EC 2.1.1.6) is one of several enzymes that degrade catecholamines such as dopamine epinephrine and norepinephrine. In humans catechol-O-methyltransferase protein is encoded by the COMT gene. As the […]

RecBCD (EC 3.1.11.5 Exonuclease V Escherichia coli exonuclease V E. coli exonuclease V gene recBC endoenzyme RecBC deoxyribonuclease gene recBC DNase gene recBCD enzymes) is an enzyme of the E. […]

Cyclins are a family of proteins that control the progression of cells through the cell cycle by activating cyclin-dependent kinase (Cdk) enzymes.

Bcl-2 (B-cell lymphoma 2) encoded in humans by the BCL2 gene is the founding member of the Bcl-2 family of regulator proteins that regulate cell death (apoptosis) by either inducing […]

An aminoacyl tRNA synthetase (aaRS) is an enzyme that catalyzes the esterification of a specific amino acid or its precursor to one of all its compatible cognate tRNAs to form […]

Dynein is a motor protein (also called molecular motor or motor molecule) in cells which converts the chemical energy contained in ATP into the mechanical energy of movement. Dynein transports […]

A kinesin is a protein belonging to a class of motor proteins found in eukaryotic cells. Kinesins move along microtubule filaments and are powered by the hydrolysis of ATP (thus […]

In humans gastrin is a peptide hormone that stimulates secretion of gastric acid (HCl) by the parietal cells of the stomach and aids in gastric motility.
