Summary

THE EFFECTS OF ETHYLENE CONCENTRATION ON PECTINMETHYLESTERASE (PME) WERE STUDIED. DATA PRESENTED SHOWED THAT A CONCENTRATION OF 100 MICROL/L ETHYLENE IN THE ATMOSPHERE ABOVE THE ENZYME HAD A STABILIZING EFFECT ON PME AT 279 K (6 DEG C) WHILE IT APPARENTLY SUPPRESSED PME ACTIVITY AT 298 K (25 DEG C). THE EFFECTS OF BOTH TEMPERATURE AND ETHYLENE ON PME ACTIVITY WERE REVERSIBLE PHENOMENA.
