The role of ArgK in arginine transport needs to be reexamined. Characterization of the ArgK ortholog MeaB strongly suggests that ArgK is actually involved in protecting Mcm from inactivation and that ArgK may bind to Mcm. MeaB and Mcm are fused in some organisms. MeaB of M. extorquens binds and hydrolyzes GTP. ArgK is a homolog of the human disease gene MMAA, implicated in methylmalonic aciduria. Part of a four gene operon encoding enzymes converting succinate to propionate. ATPase, but not protein kinase, activity is reportedly required for arginine transport. ArgK does not have predicted transmembrane segments typical of a membrane protein.[4]
