Plasmid-mediated sucrose metabolism in Escherichia coli: characterization of scrY, the structural gene for a phosphoenolpyruvate-dependent sucrose phosphotransferase system outer membrane porin.

Abstract excerpt

The scrY gene, part of the pUR400-borne sucrose regulon, appeared to be transcribed from its own promoter, with the transcriptional start site located 58 bp upstream from the initiation codon. An open reading frame encoding a polypeptide of 505 amino acid residues (Mr 55,408) was identified. The first 22 amino acid residues formed a leader sequence typical of those found in other procaryotic outer membrane and...
