The ms2io6A37 modification of tRNA in Salmonella typhimurium regulates growth on citric acid cycle intermediates
The modified nucleoside 2-methylthio-N-6-isopentenyl adenosine (ms(2)i(6)A) is present in position 37 (adjacent to and 3' of the anticodon) of tRNAs that read codons beginning with U except tRNA(I,V)(Ser) in Escherichia coli, In Salmonella typhimurium , 2-methylthio-N-6-(cis-hydroxy)isopentenyl adenosine (ms(2)io(6)A; also referred to as 2-methylthio cis-ribozeatin) is found in tRNA, most likely i
