Role of helix B residues in interfacial activation of a bacterial phosphatidylinositol-specific phospholipase C.

Biochemistry - 8 Apr 2008

Guo Su, Zhang Xin, Seaton Barbara A, Roberts Mary F

Abstract excerpt

The Bacillus thuringiensis phosphatidylinositol-specific phospholipase C (PI-PLC), an interfacial enzyme associated with prokaryotic infectivity, is activated by binding to zwitterionic surfaces, particularly phosphatidycholine (PC). Two tryptophan residues (Trp47 in the two-turn helix B and Trp2...
