• PubMed Abstract: 
  

Glutamate mutase is an adenosylcobamide (coenzyme B12) dependent enzyme that catalyzes the reversible rearrangement of (2S)-glutamate to (2S,3S)-3-methylaspartate. The enzyme from Clostridium tetanomorphum comprises two subunits (of 53.7 and 14.8 kDa) and in its active form appears to be an alpha 2 beta 2 tetramer. The smaller subunit, termed MutS, has been characterized as the B12-binding component. Knowledge on the structure of a B12-binding apoenzyme does not exist.
