Rabbit skeletal muscle myosin subfragment-1 (S-1) was reacted with dimethyl(2-hydroxy-5-nitrobenzyl)sulfonium bromide (DHNBS) resulting in modification of 0.8 tryptophan residues per S-1. In order to assign the most reactive tryptophan of the 5 S-1 tryptophans, antibodies were raised in rabbits against

Brequinar and the active metabolite of leflunomide, A77 1726, have been clearly shown to inhibit human dihydroorotate dehydrogenase (DHODH), but conflicting mechanisms for their inhibition have been reported. DHODH catalyses the conversion of dihydroorotate (DHO) to orotate concurrent with the

Heparin has been shown to exhibit lower affinity for the antithrombin-thrombin complex than for antithrombin alone (Carlstrom, A.-S., Lieden, K., and Bjork, I. (1977) Thromb. Res. 11, 785-797), suggesting that structural alterations in antithrombin may accompany its reaction with thrombin.
