Blumenthal, Donald K. | Phosphorylation of cardiac troponin by guanosine 3':5'-monophosphate-dependent protein kinase. | Homogeneous cGMP-dependent protein kinase catalyzes the rapid incorporation of phosphate, specifically into the inhibitory subunit of purified cardiac troponin with a maximal incorporation of 1 mol of phosphate/mol of troponin. When troponin was incubated in the presence of both cGMP- and cAMP-depen... | Protein Kinases | 1978-01-25 |

Poulter, Charles Dale | Prenyltransferase. Kinetic studies of the 1'-4 coupling reaction with avian liver enzyme. | Prenyltransferase catalyzes the sequential, irreversible 1'-4 condensation of isopentenyl-PP with dimethylallyl-PP and geranyl-PP to yield farnesyl-PP. A kinetic study shows substrate inhibition by isopentenyl-PP at concentrations above 0.7 microM when the concentration of geranyl-PP is 1.0 microM o... | Birds; Kinetics; Structure-Activity Relationship; Substrate Specificity | 1979-10-10 |
