Indolocarbazoles have been identified as novel inhibitors of protein kinase C (PKC), with Gö 6976 as one of its most potent and selective representatives. Recombinant PKC isozymes alpha, beta 1, delta, epsilon, and zeta were used in in vitro kinase assays to investigate Gö 6976 with respect to isozyme-specific PKC inhibition. Gö 6850, identical with GF 109203X, another PKC-specific kinase inhib...
Amylopectin is a highly branched, organized cluster of glucose polymers, and the major component of rice starch. Synthesis of amylopectin requires fine co-ordination between elongation of glucose polymers by soluble starch synthases (SSs), generation of branches by branching enzymes (BEs), and removal of misplaced branches by debranching enzymes (DBEs). Among the various isozymes having a role ...
Protein kinase C (PKC) isozymes are a family of serine/threonine protein kinases categorized into three subfamilies: classical, novel, and atypical. PKC isozymes, whose expression is cell type-specific and developmentally regulated, are key transducers in many agonist-induced signaling cascades. To date at least 10 different PKC isotypes have been identified and are believed to play distinct re...
The lipase activity of most phospholipases C (PLCs) is basally repressed by a highly degenerate and mostly disordered X/Y linker inserted within the catalytic domain. Release of this auto-inhibition is driven by electrostatic repulsion between the plasma membrane and the electronegative X/Y linker. In contrast, PLC-γ isozymes (PLC-γ1 and -γ2) are structurally distinct from other PLCs because mu...
The rate constant of modification of a specific thiol group, SH 2, with Nethylmaleimide (NEM) has been used to estimate the conformational change in the local area containing SH2 (SH2 region) of skeletal myosin as a structural probe. The rate of Mg 2§ SH 2 modification of subfragment-1 (S-l) isozymes was regulated by Ca 2 § in the pCa range below 6.4 and was not regulated in the pCa range above...
The expression of lipoxygenases (LOXs) is known to be developmentally regulated in soybeans (Glycine max. [L.] Merr.). Hormones have been firmly established as being involved in the growth and developmental processes of a number of plant species. Correlation between the expression of LOXs and the development and germination of soybean embryos suggests that plant hormones may affect the expressi...
Diphenhydramine is widely used as an over-the-counter antihistamine. However, the specific human cytochrome P450 (P450) isozymes that mediate the metabolism of diphenhydramine in the range of clinically relevant concentrations (0.14-0.77 microM) remain unclear. Therefore, P450 isozymes involved in N-demethylation, a main metabolic pathway of diphenhydramine, were identified by a liquid chromato...
