additional information cation-Pi interactions contribute to substrate recognition in gamma-butyrobetaine hydroxylase catalysis. BBOX contains an aromatic cage for the recognition of the positively charged trimethylammonium group of the gamma-butyrobetaine substrate. Substrate analogues (3-carboxypropyl)(trimethyl)phosphanium and (3-carboxypropyl)(trimethyl)arsanium with P and As substituting for N in the trimethylammonium group are good BBOX substrates, which follow the efficiency trend N+ >P+ >As+. An uncharged carbon analogue N-(3-hydroxypyridine-2-carbonyl)-S-[(pyridin-2-yl)methyl]-L-cysteine of gamma-butyrobetaine is not a BBOX substrate. Importance of the energetically favorable cation-Pi interactions in productive substrate recognition. Homology modeling of binding modes and structures of (3-carboxypropyl)(trimethyl)phosphanium and (3-carboxypropyl)(trimethyl)arsanium to psBBOX using an X-ray crystal structure of human BBOX in complex with ZnII, N-oxalylglycine, and gamma-butyrobetaine, PDB ID 3O2G, quantum mechanical calculations and docking simulations.

General Information

General Information Comment Organism
evolution the enzyme belongs to the 2-oxoglutarate/Fe(II) dependent oxygenase family Pseudomonas sp.
physiological function gamma-butyrobetaine hydroxylase (BBOX) is a nonheme Fe(II)- and 2-oxoglutarate-dependent oxygenase that catalyzes the stereoselective hydroxylation of an unactivated C-H bond of gamma-butyrobetaine in the final step of carnitine biosynthesis Pseudomonas sp.
