Family members were previously thought to be ArgK proteins acting as ATPase enzymes and kinases. They are now believed to be methylmalonyl Co-A mutase-associated GTPase MeaB. Structural studies of MeaB and the human ortholog (methylmalonyl associated protein A) MMAA, reveal alpha-helical domains at the N- and C-termini as well as a Ras-like GTPase domain. Mutational analysis of MeaB, show prohibited growth in Methylobacterium due to the inability to convert methylmalonyl-CoA to succinyl-CoA caused by an inactive form of methylmalonyl-CoA mutatase (mcm). In humans, mutations in (MMAA) are associated with the fatal disease methylmalonyl aciduria [1].	Domain
