Escherichia coli K-12 substr. MG1655 Polypeptide: fatty acid/phospholipid synthesis protein

Gene: plsX Accession Numbers: EG11437 (EcoCyc), b1090, ECK1076

Regulation Summary Diagram: ?

Regulation summary diagram for plsX

A mutation in plsX is required for the sn-glycerol-3-phosphate auxotrophic phenotype of a plsB mutant strain [Larson84]. A plsX ygiH double deletion is lethal [Yoshimura07]. Yoshimura et al. hypothesize that PlsX and YgiH play a role in regulating the intracellular concentration of acyl-ACP [Yoshimura07].

Transcript levels and operon structure of plsX have been analyzed [Podkovyrov95, Zhang98a].

Locations: cytosol

Map Position: [1,146,844 -> 1,147,914] (24.72 centisomes, 89°)
Length: 1071 bp / 356 aa

Molecular Weight of Polypeptide: 38.214 kD (from nucleotide sequence)
