IntEnz Enzyme Nomenclature


Accepted name:
isochorismate lyase
Other names:
salicylate biosynthesis protein pchB
pyochelin biosynthetic protein PchB
isochorismate pyruvate lyase
Systematic name:
isochorismate pyruvate-lyase (salicylate-forming)



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.
