Escherichia coli K-12 substr. MG1655 Polypeptide: conserved protein



Gene: ppdB Accession Numbers: EG11156 (EcoCyc), b2825, ECK2821

Synonyms: ygdC

Regulation Summary Diagram: ?

Summary:
A ppdAB mutant does not exhibit defects in chemotaxis or flagellar motility [Park01]. Overproduction of PpdAB does not result in defects in chemotaxis or flagellar motility [Park01].

PpdB: "prepilin peptidase dependent"

Regulation has been described [Park01]. Transcription is sigmaF (FliA) regulated [Park01]. Transcription is regulated by FlhDC [Park01].

Locations: cytosol, pilus

Map Position: [2,961,175 <- 2,961,738] (63.82 centisomes)
Length: 564 bp / 187 aa

Molecular Weight of Polypeptide: 20.519 kD (from nucleotide sequence)
