Irreversible thermal denaturation experiments with 3 enzymes from Typha latifolia populations native to distinct thermal climates produced 3 different responses: (1) malate dehydrogenase was much more resistant to high temperature inactivation when obtained from plants native to a hot climate, (2) glutamate-oxaloacetate transaminase was quite resistant to thermal denaturation regardless of origin, and (3) aldolase was rapidly inactivated by heat regardless of origin.
