Ramírez-Santos, J and Gómez-Eichelmann, MC (1998) Identification of sigma 32-like factors and ftsX-rpoH gene arrangements in enteric bacteria. Can. J. Microbiol. 44:565-8

Abstract

Western blot analyses using anti-Escherichia coli K-12 sigma 32 antibodies and Southern blot analyses using rpoH and ftsX DNA probes were performed using different enteric bacteria. Results show that the bacterial strains analysed have sigma 32-like transcription factors and ftsX and rpoH homologs in a similar map position. Although the presence of sigma 32-like factors seems to be extended to all Proteobacteria, rpoH and ftsX homologs seem to be present as neighbors in the genome only in the enteric bacteria.
