E. coli biotin ligase
(BirA) is highly specific in covalently attaching biotin to the 15
amino
acid AviTag peptide. This recombinant protein was biotinylated in
vivo
by AviTag-BirA technology, which method is BriA catalyzes amide
linkage
between the biotin and the specific lysine of the AviTag.

A cytochrome P450 monooxygenase involved in the metabolism of endocannabinoids and steroids. Mechanistically, uses molecular oxygen inserting one oxygen atom into a substrate, and reducing the second into a water molecule, with two electrons provided by NADPH via cytochrome P450 reductase (NADPH--hemoprotein reductase). Catalyzes the epoxidation of double bonds of arachidonoylethanolamide (anandamide) to 8,9-, 11,12-, and 14,15-epoxyeicosatrienoic acid ethanolamides (EpETrE-EAs), potentially modulating endocannabinoid system signaling. Hydroxylates steroid hormones, including testosterone at C-16 and estrogens at C-2. Plays a role in the oxidative metabolism of xenobiotics, including plant lipids and drugs. Acts as a 1,4-cineole 2-exo-monooxygenase.; Allele 2B6*9: Has low affinity for anandamide and can only produce 11,12 EpETrE-EAs.
