/enzymology. /enzyme activity . /enzymes . Used with organisms, except vertebrates, and with organs and tissues. It is also used with diseases for enzymes during the course of the disease, but excludes diagnostic enzyme tests, for which "diagnosis" is used. . 1.00
Enzymes. Biocatalysts . Biological molecules that possess catalytic activity. They may occur naturally or be synthetically created. Enzymes are usually proteins, however CATALYTIC RNA and CATALYTIC DNA molecules have also been identified. . 1.00

Chloramphenicol O-Acetyltransferase. Chloramphenicol Transacetylase . Acetyltransferase, Chloramphenicol . Chloramphenicol O Acetyltransferase . Enzyme, CAT . O-Acetyltransferase, Chloramphenicol . Transacetylase, Chloramphenicol . CAT Enzyme . Chloramphenicol Acetyltransferase . An enzyme that catalyzes the acetylation of chloramphenicol to yield chloramphenicol 3-acetate. Since chloramphenicol 3-acetate does not bind to bacterial ribosomes and is not an inhibitor of peptidyltransferase, the enzyme is responsible for the naturally occurring chloramphenicol resistance in bacteria. The enzyme, for which variants are known, is found in both gram-negative and gram-positive bacteria. EC 2.3.1.28. . 0.73
AlkB Enzymes. AlkB Homologs . Alkylated DNA Repair Protein AlkB Homologs . Alkylation Repair Homolog Proteins . Alkylation Repair Homologs . Enzymes, AlkB . A family of alpha- KETOGLUTARIC ACID and Fe(II)-dependent dioxygenases that are homologous to AlkB, an enzyme that repairs alkylated nucleic acids in E. coli. The mammalian homologs have diverse substrate specificities and functions that include DNA REPAIR, generating unique wobble modifications in URIDINE tRNA, demethylation of nucleotides in DNA and RNA, and demethylation of LYSINE residues on certain proteins, including ACTIN and histones (HISTONE CODE). . 0.72
Cytochrome P450 Family 2. CYP2 Enzymes . CYP2 Family . A cytochrome P450 enzyme family that includes members which function in the metabolism of STEROIDS; COUMARINS; and NICOTINE. . 0.71
