Nucleotide sequence and transcriptional products of the csg locus of Myxococcus xanthus.

Abstract

The csg locus of Myxococcus xanthus appears to control the production of an intercellular signal that is essential for development. The complete nucleotide sequence of a clone containing the csg locus was determined by the dideoxy-chain termination method. Pattern recognition analyses of the DNA sequence revealed the presence of two protein-coding regions that are convergently oriented and separated by only 8 nucleotides. Tn5 lac insertions into this clone detected two transcriptional units that are transcribed in a convergent fashion and whose expression increases during development. The two genes represented by these protein-coding regions and transcriptional units have been designated csgA and fprA. Northern (RNA) blot analyses detected an 800-nucleotide RNA specific to the csgA gene and a 900-nucleotide RNA specific to the fprA gene. Our results, along with mutational studies, identify csgA as the gene involved in cell communication. The function of the fprA gene is described in an accompanying paper (L. J. Shimkets, J. Bacteriol. 172:24-30, 1990).
