This family consists of monooxygenase components such as MmoB methane monooxygenase (EC:1.14.13.25) regulatory protein B. When MmoB is present at low concentration it converts methane monooxygenase from an oxidase to a hydroxylase and stabilises intermediates required for the activation of dioxygen [1]. Also found in this family is DmpM or Phenol hydroxylase (EC:1.14.13.7) protein component P2, this protein lacks redox co-factors and is required for optimal turnover of Phenol hydroxylase [3].
