pubmed:abstractText
Escherichia coli penicillin-binding protein 5 (PBP5) is anchored to the periplasmic face of the inner membrane via a C-terminal amphiphilic alpha-helix. The results of washing experiments have suggested an electrostatic contribution to the anchoring mechanism which may involve the cationic region of the C-terminal alpha-helix. Similarities between this anchor domain and some surface active agents, such as melittin, suggest that the cationic region of the PBP5 anchor may require the presence of anionic phospholipids for membrane interaction. Washing experiments performed on membranes of HDL11, an E. coli mutant in which the expression of the major anionic phospholipids is under lac control, found no such requirement. The results are discussed in relation to the hypothesis that the cationic region may interact with other sources of negative charge, possibly arising from a PBP complex.
