Publication Abstract from PubMed The substrate specificity of alpha-lytic protease has been changed dramatically, with a concomitant increase in activity, by replacing an active-site Met with Ala. The substrate specificity of both this mutant and another similar mutant are extraordinarily broad. X-ray crystallographic analysis shows that structural plasticity, a combination of alternate side-chain conformations and binding-site flexibility, allows both large and small substrates to be well accommodated. Structural plasticity broadens the specificity of an engineered protease.,Bone R, Silen JL, Agard DA Nature. 1989 May 18;339(6221):191-5.
