Invertase and Disulphide Bridges in the Yeast Wall Free

Abstract

Surmmary

Invertase released from (Jorgensen) by either breakage or thiol treatment exhibited identical electrophoretic characteristics. Evidence was obtained against an indirect chemical effect of breakage on the release of invertase from yeasts. Electron microscopy revealed no obvious differences between walls of and other yeasts. A model is proposed in which invertase is not bonded to the wall but is retained by structures requiring intact S—S linkings.
