Name LPS_assembly_LapB
Scope
Bacteria; Pseudomonadota
Template P0AB58 (LAPB_ECOLI)

Propagated annotation [?]


Identifier, protein and gene names [?]

Identifier
LAPB
Protein name
RecName: Full=Lipopolysaccharide assembly protein B;
Gene name
lapB

Comments [?]

Function Modulates cellular lipopolysaccharide (LPS) levels by regulating LpxC, which is involved in lipid A biosynthesis. May act by modulating the proteolytic activity of FtsH towards LpxC. May also coordinate assembly of proteins involved in LPS synthesis at the plasma membrane.
Subcellular location Cell inner membrane; Single-pass membrane protein; Cytoplasmic side.
Similarity Belongs to the LapB family.
