Competitive inhibitors of the angiotensinconverting enzyme from the venom of the viperEchis multisquamatus

The mechanism of the inhibition of the angiotensin-converting enzyme (ACE, E. C. 3.4.15.1) by homogeneous peptides of the venom of the Central Asian viperEchis multisquamatus Ch. has been determined, and the inhibition constants have been measured, by means of an analysis of Lineweaver-Burk graphs.
