2.9.1.3	selenophosphate + geranyl diphosphate + 5-methylaminomethyl-2-thiouridine34 in tRNA + H2O	-
2.9.1.3	selenophosphate + geranyl diphosphate + 5-methylaminomethyl-2-thiouridine34 in tRNA + H2O	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
2.9.1.3	selenophosphate + geranyl diphosphate + 5-methylaminomethyl-2-thiouridine34 in tRNA + H2O	ybbB is required in vivo for the specific substitution of selenium for sulfur in 2-thiouridine residues in Escherichia coli tRNA. This modified tRNA nucleoside, 5-methylaminomethyl-2-selenouridine (mnm5se2U), is located at the wobble position of the anticodons of tRNALys, tRNAGlu, and tRNA1Gln
