Protein Variants

Protein Variants Comment Organism
G67E mutation in the rhodanese domain increases the intrinsic low geranylation activity of the wild type MnmH Salmonella enterica subsp. enterica serovar Typhimurium
G67E/K155A the mutant enzyme does not transfer in vitro a geranyl group from geranylpyrophosphate to tRNA Salmonella enterica subsp. enterica serovar Typhimurium

selenophosphate + geranyl diphosphate + 5-methylaminomethyl-2-thiouridine34 in tRNA + H2O Salmonella enterica subsp. enterica serovar Typhimurium the enzyme converts 5-methylaminomethyl-2-uridine and 5-carboxymethylaminomethyl-2-uridine to the respective selenouridine forms in a two-step process that involves geranylation and subsequent phosphoselenation of the resulting geranylated intermediates. The resultant seleno-phosphorylated uridine intermediates further react with a water molecule to release a phosphate anion and 2-selenouridine tRNA 5-methylaminomethyl-2-selenouridine34 in tRNA + (2E)-3,7-dimethylocta-2,6-diene-1-thiol + diphosphate + phosphate
