| + | == Publication Abstract from PubMed == | ||
| + | Anaerobic degradation of hydrocarbons was discovered a decade ago, and ethylbenzene dehydrogenase was one of the first characterized enzymes involved. The structure of the soluble periplasmic 165 kDa enzyme was established at 1.88 A resolution. It is a heterotrimer. The alpha subunit contains the catalytic center with a molybdenum held by two molybdopterin-guanine dinucleotides, one with an open pyran ring, and an iron-sulfur cluster with a histidine ligand. During catalysis, electrons produced by substrate oxidation are transferred to a heme in the gamma subunit and then presumably to a separate cytochrome involved in nitrate respiration. The beta subunit contains four iron-sulfur clusters and is structurally related to ferredoxins. The gamma subunit is the first known protein with a methionine and a lysine as axial heme ligands. The catalytic product was modeled into the active center, showing the reaction geometry. A mechanism consistent with activity and inhibition data of ethylbenzene-related compounds is proposed. | ||
