A case of infantile digital fibromatosis was studied with regard to the distribution of -SH groups and SS linkages, using N-(7-dimethylamino-4-methyl-3-coumarinyl) maleimide (DACM) stain. Tumor cells showed a strong fluorescence in the cytoplasm from the -SH stain. A brilliant -SH

To elucidate the morphogenesis of cornoid lamellae (CL) in porokeratosis, skin lesions of three cases of disseminated superficial actinic porokeratosis and a case of linear porokeratosis were examined. By N-(7-dimethylamino-4-methyl-3-coumarinyl)maleimide staining, SH groups were present in the living layer of

Our previous studies suggested that in a tetrameric enzyme aspartase, Cys-140 and Trp-430 are located at or near the catalytic and activator sites, respectively. To estimate the distance between these two sites, fluorescence energy transfer between a single tryptophan (Trp-430)

We have studied the distribution of SH groups and SS linkages in solar elastosis, in comparison with that in aged and juvenile sun-unexposed skin, using N-(7-dimethylamino-4-methyl-3-coumarinyl) maleimide (DACM) stain. In heavy solar elastosis we found increased fluorescence for SS bonds

We studied the transition metal ion requirements for activity and sulfhydryl group reactivity in phospho enol pyruvate carboxykinase (PEP-carboxykinase; ATP:oxaloacetate carboxylase (transphosphorylating), EC 4.1.1.49), a key enzyme in the energy metabolism of the protozan parasite Trypanosoma (Schizotrypanum) cruzi.
