Phenotypes of a mutant
inactivation of ''[gene|66A6EC4F6CB91EE741BB9D7646913FF3EE602BD7|thdF]'' reduces sporulation efficiency to 21.9% that of wild type cells; longer mother cells, some with aberrant septa and forespores [Pubmed|26735940]The protein
Catalyzed reaction/ biological activity
Binds and hydrolyzes GTP and readily exchanges GDP for GTPProtein family

cytoplasm (according to Swiss-Prot)Additional information
Information on the corresponding protein from ''E. coli'': [http://BioCyc.org/ECOLI/NEW-IMAGE?type=ENZYME&object=EG10997-MONOMER EcoCyc]MnmE required for wild-type 5-methylaminomethyl-2-thiouridine modification of tRNA, interacts with [protein|7809B4F5B9172EBB6C91BDE7B673FB08E82763FF|GidA]. MnmE also appears to play a role in oxidation of thiophene and furan compounds and regulates glutamate-dependent acid resistance.Expression and Regulation
