PMID: 14729702
tRNA from Salmonella enterica serovar Typhimurium contains five thiolated nucleosides, 2-thiocytidine (s(2)C), 4-thiouridine (s(4)U), 5-methylaminomethyl-2-thiouridine (mnm(5)s(2)U), 5-carboxymethylaminomethyl-2-thiouridine (cmnm(5)s(2)U), and N-6-(4-hydroxyisopentenyl)-2-methylthioadenosine (ms(2)io(6)A). The levels of all of them are significantly reduced...
