PspB

• PFAM accession number: PF06667
• Interpro abstract (IPR009554):

  This family consists of several bacterial phage shock protein B (PspB) sequences. The phage shock protein (psp) operon is induced in response to heat, ethanol, osmotic shock and infection by filamentous bacteriophages [ (PUBMED:1712397) ]. Expression of the operon requires the alternative sigma factor sigma54 and the transcriptional activator PspF. In addition, PspA plays a negative regulatory role, and the integral-membrane proteins PspB and PspC play a positive one [ (PUBMED:12562786) ].

• GO process: phage shock (GO:0009271), regulation of transcription, DNA-templated (GO:0006355)
