cyclohexa-1,5-diene-1-carbonyl-CoA:ferredoxin oxidoreductase (aromatizing, ATP-forming)

An iron-sulfur protein. Requires Mg2+ or Mn2+. Inactive towards aromatic acids that are not CoA esters but will also catalyse the reaction: ammonia + acceptor + 2 ADP + 2 phosphate = hydroxylamine + reduced acceptor + 2 ATP + H2O. In the presence of reduced acceptor, but in the absence of oxidizable substrate, the enzyme catalyses the hydrolysis of ATP to ADP plus phosphate.

the detection of benzoyl-CoA reductase genes from bacterial pure cultures and environmental samples can be used to determine the genetic capability for anaerobic degradation of aromatic compounds and to monitor the anaerobic degradation of many different aromatic compounds in the environment. Sequence divergence of benzoyl-CoA reductase genes could be used to identify and distinguish among different bacterial populations degrading aromatic compounds in various environments. Microarray or real-time PCR amplification with specific primers for different types of benzoyl-CoA reductase genes could be applicable in environmental studies to determine which types are dominant and activated in particular environmental conditions and to evaluate the population response to variation in environmental factors.
