, and continued with much other work on heme proteins.

Medical and physiological work

In keeping with his medical qualifications, much of Gibson's early work had medical or physiological relevance.

Cooperativity

During the period when protein and enzyme cooperativity was at the center of biochemical interest Gibson studied it in the context of abnormal hemoglobins.

Rapid reactions

Gibson made major contributions to the development of methods for studying rapid reactions, and their application to hemoglobin.

Other proteins

Other work concerned enzymes such as "

diaphorase Diaphorase may refer to: * Cytochrome b5 reductase, an enzyme * NADH dehydrogenase, an enzyme * NADPH dehydrogenase, an enzyme {{Short pages monitor
