ETHYLBENZENE DEHYDROGENASE FROM AROMATOLEUM AROMATICUM
Overview
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.
