Abstract

The presence of angiotensin I-converting enzyme-like activity (ACELA) was investigated in whole body homogenates of Branchiostoma lanceolatum using a highly sensitive fluorimetric assay. The measured enzyme activity was inhibited by the two angiotensin converting enzyme inhibitors, captopril and enalapril, suggesting a biochemical pathway that could generate the angiotensins observed in the central nervous system of amphioxus.
