- Abstract
The nucleotide sequence of the agp gene, which encodes a periplasmic glucose-1-phosphatase, was determined. The deduced amino acid sequence corresponds to a 413-amino-acid-residue polypeptide with a typical hydrophobic signal sequence of 22 amino acids. The mature protein lacks the N-terminal signal peptide and has a calculated Mr of 43,514. Its promoter was defined by primer extension of the mRNA made in vivo. Like many genes under positive control, its -35 promoter region does not match the consensus. The agp gene is both preceded and followed by transcription termination signals, so it appears to be transcribed as a single unit.
