tRNA pseudouridine 55 (psi 55) synthase, the enzyme that is specific for the conversion of U55 to psi 55 in the m5U psi CG loop in most tRNAs, has been purified from Escherichia coli and cloned. On SDS gels, a single polypeptide chain with a mass of 39.7 kDa was found. The gene is a previously described open reading frame, p35, located at 68.86 min on the E. coli chromosome between the infB and rpsO genes. The proposed name for this gene is truB. There is very little protein sequence homology… CONTINUE READING
