Zero-order Ultrasensitivity in Interconvertible Enzyme Systemsse are to be elicited by relatively small changes in stimulus, i.e. substrate or effector in the case of enzymes (Koshland ., 1982). An important role is nevertheless retained in metabolic systems by other reactions in the pathway since these will determine whether any abrupt change is propagated be

Metabolic Control by the Cyclic Cascade Mechanism: a Study of , Glutamine Synthetasece the amide nitrogen atom of glutamine is a preferred nitrogen source for the biosynthesis of virtually all amino acids, purine and pyrimidine nucleotides, NAD and glucosamine-6-phosphate, it is rigorously regulated in bacteria which synthesize their own amino acids.

Properties Needed for the Enzymes of an Interconvertible Cascade to Generate a Highly Sensitive Respnsitivity in the response of a pathway to an effector. Consequently the understanding of the mechanisms that allow a high degree of sensitivity should constitute a major goal of any theory of metabolic control. Cooperativity in the response of an enzyme to an effector is undoubtedly an important mec

The Spread Relation and Its Applications,o some, at least, I am considered a grandfather of the field. I am not sure how I came to be a grandfather without ever being a father. Yet let that be, for I accept the accolade with sincere appreciation even though I think it partly, if not wholly, apocryphal. But if there are grandfathers, there
