The reagent 2-nitro-5-thiocyanatobenzoic acid (NTCB) is commonly used to cyanylate and cleave proteins at cysteine residues, but this two-step reaction requires lengthy incubations and produces highly incomplete cleavages. In previous reports, incomplete cleavage was attributed to a competing beta-elimination reaction

Keratin-associated proteins (KAPs) are important constituents of the wool cuticle, comprised of the endo-, exocuticle and a-layers, which contribute significantly to the fibre's molecular and mechanical characteristics. Relatively little is known about the distribution of specific KAPs across these layers

The role of transducin sulfhydryl groups was examined by chemical modification with four different reagents: 4-acetamido-4'-maleimidyl-stilbene-2, 2' disulfonic acid (AMDA); 4-vinyl pyridine (VP); 2-nitro-5-thiocyano benzoic acid (NTCBA); and 2, 5-dimethoxystilbene-4'-maleimide (DM). All these compounds rapidly inhibited the [3H]GMPpNp-binding activity of
