title: Two distinct isocitrate lyases from a pseudomonas species.
abstract: The isocitrate lyases of acetate- and methylamine-grown Pseudomonas MA (Shaw strain) were studied. They were shown to be different by a variety of physical criteria including chromatographic elution patterns, heat inactivation kinetics, pH variation of Km values, and migration on polyacrylamide gels. The implications and significance of the existence of two enzymes in relation to the role of isocitrate lyase in methylamine utilization is discussed.
