Lineage
Bacteria; Pseudomonadota; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Escherichia
Also known as
ECK1300
Summary
PspB and PspC together act to activate transcription of the psp operon induced by infection with bacteriophage, exposure to ethanol, or osmotic shock (but not heat treatment); PspC is essential for this activation, whereas PspB is not strictly required . [More information is available at EcoCyc: EG10777].

What's a GeneRIF?
  1. ArcB directly interacts with PspB, possibly by means of the PspB leucine zipper motif, thereby allowing cross-communication between the two systems.
