Abstract

The DNA nucleotide sequence of four genes for the phosphate-specific transport system of Escherichia coli is reported. Along with the DNA sequence for the phoS gene reported previously (Surin et al., J. Bacteriol. 157:772-778, 1984; Magota et al., J. Bacteriol. 157:909-917, 1984), this study completes the nucleotide sequence of the phosphate-specific transport region. The complete sequence (including phoS) contains five open reading frames oriented in the same direction, each preceded by a putative ribosome-binding site near the presumed translation initiation codon ATG. The complete sequence is transcribed counterclockwise, in the order phoS pstC pstA pstB phoU. Genetic complementation shows that of the four open reading frames in the new sequence, three correspond to known mutant alleles; the fourth, which was designated pstC, has not been described before and could not be related to any known mutant allele. We have confirmed that pstA was allelic to phoT32. The pstC, pstB, and phoU gene products were identified as peripheral membrane proteins. The pstA gene product appears to be an integral membrane protein.
