Phosphorylase phosphatase. Interconversion of active and inactive forms.

Regulation of Rhodospirillum rubrum nitrogenase activity. Properties and interconversion of active and inactive Fe protein.

Interconversion between active and inactive TATA-binding protein transcription complexes in the mouse genome

The TATA binding protein (TBP) plays a pivotal role in RNA polymerase II (Pol II) transcription through incorporation into the TFIID and B-TFIID complexes. The role of mammalian B-TFIID composed of TBP and B-TAF1 is poorly understood. Using a complementation system in genetically modified mouse cells where endogenous TBP can be conditionally inactivated and replaced by exogenous mutant TBP coup...

Comparison of Quality of Life between Active and Inactive Workers

Introduction: Numerous important factors such as physical and mental condition affect the quality of life Job stress is one of the key factors in decreasing productivity in organizations. Given the positive effects of physical activity on quality of life, this study aimed to compare the quality of life between active and inactive workers (case study). Methods: This study was a cross-sectional ...

Mammalian phosphorylase phosphatase.

Phosphorylase phosphatase converts phosphorylase a into phosphorylase b. It was the first interconverting enzyme to be discovered (Cori & Green, 1943) and is the best characterized of the protein phosphatases involved in the regulation of glycogen metabolism, although its enzymology is still incompletely understood (for a review see Lee et al., 1976). We have developed a procedure for the isola...

Rabbit skeletal muscle protein phosphatase(s). Identity of phosphorylase and synthase phosphatase and interconversion to the ATP-Mg-dependent enzyme form.

A high molecular weight protein phosphatase was purified from rabbit skeletal muscle displaying activity toward phosphorylase Q and synthase b isolated from the same tissue. The extensively purified enzyme was shown to have a M, = 260,000 by gel filtration and dissociated in sucrose density gradient centrifugations into a M, = 70,000 species. The 70,000-dalton enzyme form, resulting from prepar...
