Maximum rates and Km values were recently reported for seven aldehydes as substrates of rabbit muscle glyceraldehyde-3-phosphate dehydrogenase 51). Values for which might have provided further evidence for the conclusion that the mechanism is ordered, were not reported, however.

On the other hand, a number of native proteins tested were found to be better substrates for cathepsin M than for cathepsin B (Table IV). Muscle and liver aldolases were inactivated by cathepsins M and B at comparable rates (Table IV) but yeast glucose-6-phosphate dehydrogenase was inactivated much more rapidly by cathepsin M and neither rabbit liver pyruvate kinase nor rabbit muscle glyceraldehyde-3-phosphate dehydrogenase was inactivated on incubation with cathepsin B.

The basis of the action of iodoacetate on muscle contraction was uncovered by Dickens and Rapkine (ca. 1933). They found iodoacetate alkylated SH groups on proteins, especially those in glyceraldehyde 3-phosphate dehydrogenase (G-3-PDH). When the enzyme was inhibited precursors accumulated—hexose mono- and diphosphates—as in Lundsgaard s experiments.

For glyceraldehyde-3-phosphate dehydrogenase, conflicting conclusions have been reached by different workers (47 49). From one analysis of initial rate data, for the pig muscle enzyme, it appears that with glycer-aldehyde as substrate the mechanism is random (SO), whereas with glyceraldehyde 3-phosphate there is random combination of this substrate and NAD followed by phosphate as the compulsory third substrate (48). On the other hand, inhibition studies with the rabbit muscle enzyme indicate an ordered mechanism in which NAD is the first and acyl acceptor the last substrate to combine (51). More detailed comparative initial rate studies with the several aldehydes w hich act as substrates (Section II,E), preferably by a fluorimetric method (11,47), and isotope exchange studies at equilibrium are needed for this enzyme.
