Organism
Escherichia coli str. K-12 substr. MG1655 (strain: K-12, substrain: MG1655)
Lineage
Bacteria; Pseudomonadati; Pseudomonadota; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Escherichia
Also known as
ECK4042; yjbO
Summary
pspG is co-regulated with the psp operon and is a member of the pspF-dependent regulon. pspG is not physically linked to the psp operon, but is co-conserved. [More information is available at EcoGene: EG11933]. The PspG protein is predicted to be an inner membrane protein. [More information is available at EcoCyc: EG11933].
