Additional information

Information on the corresponding protein from E. coli: EcoCyc MnmE required for wild-type 5-methylaminomethyl-2-thiouridine modification of tRNA, interacts with GidA. MnmE also appears to play a role in oxidation of thiophene and furan compounds and regulates glutamate-dependent acid resistance.
