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 | - |
