the number of g units in php fibroblast membranes , measured by cholera toxin-dependent [ ( 32 ) p ] adp ribosylation of g-unit peptides , as well as the g-unit activity , determined by the ability of detergent extracts to reconstitute adenylate cyclase activity in g-unit-deficient s49 cyc ( - ) membranes , were found to be markedly reduced compared with control membranes ( 43 and 40 % , respectively ) , the activation of fibroblast membrane adenylate cyclase by effectors that act directly through the g unit ( guanosine triphosphate , guanosine 5'-0- [ 3-thiotriphosphate ] [ gtp-gamma-s ] , naf ) was significantly greater in control membranes than in membranes from patients with php .
