IUBMB Enzyme Nomenclature


Accepted name: isochorismate lyase

Reaction: isochorismate = salicylate + pyruvate

Other name(s): salicylate biosynthesis protein pchB; pyochelin biosynthetic protein PchB; isochorismate pyruvate lyase

Systematic name: isochorismate pyruvate-lyase (salicylate-forming)

Comments: This enzyme is part of the pathway of salicylate formation from chorismate, and forms an integral part of pathways that produce salicylate-derived siderophores, such as pyochelin and yersiniabactin.
