Gösta Pettersson (biochemist)
Gösta Pettersson is an emeritus professor in biochemistry at Lund University, Sweden. He was born in 1937 in Varberg, Sweden. He gained his Ph.D. at Lund University in 1966 on the basis of a thesis on toluquinones (natural products), and his early research was mainly concerned with fumigatin and other products of fungal metabolism. The turning point in Pettersson's career came in the wake of a kinetic study of an enzyme from Aspergillus fumigatus. This paper has had virtually no influence on the progress of biochemistry, having never been cited in half a century except for once by its author, but it marked the beginning of the work on enzymes and kinetics for which Pettersson is best known. Alcohol dehydrogenase The major experimental focus of Pettersson's work on the kinetics of enzyme-catalysed reactions was the enzyme alcohol dehydrogenase, principally the enzyme from horse liver, but to some degree from other sources, such as the insect Drosophila melanogaster. His work in this area concerned both "classical" steady-state kinetics, such as pH-dependence, as well as study of transients in the mechanism. In recognition of his contributions to the study of alcohol dehydrogenase Pettersson was invited to write a review on the topic
