Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1989
1. Myofibrils isolated from Mercenaria mercenaria were phosphorylated by endogenous kinase. Over a range of ionic strengths only paramyosin was phosphorylated. 2. Thiophosphorylation of paramyosin caused an inhibition of steady-state actin-activated ATPase activity of the myofibrils. 3. It is proposed that the endogenous kinase is the catalytic subunit

Current Opinion in Structural Biology, 1996
The two examples of phospho and dephospho proteins for which structural data were previously available (glycogen phosphorylase and isocitrate dehydrogenase) demonstrated two different mechanisms for control. In glycogen phosphorylase, activation by phosphorylation results in long-range allosteric changes.

Phosphorylation of rhodopsin: Most rhodopsin molecules are not phosphorylated
Biochemical and Biophysical Research Communications, 1974Abstract Phosphorylation of rod membrane proteins is a light-dependent reaction. Most rhodopsin molecules, however, are not phosphorylated. The protein that is highly phosphorylated (>3 moles phosphate per mole phosphorylated protein) appears to be a rhodopsin species that is different from the rest or is located in different parts of the rod ...

Non-phosphorylated intermediates in oxidative phosphorylation
Biochimica et Biophysica Acta, 1963Abstract 1. 1. This paper is concerned with the study of the formation of non-phosphorylated intermediates in digitonin particles prepared from rat-liver mitochondria. 2. 2. Digitonin particles were preincubated with either β-hydroxybutyrate, sucinate or ferrocytochrome c for a short time at 20°.

Evidence of a phosphorylated intermediate in mitochondrial oxidative phosphorylation
Biochemical and Biophysical Research Communications, 1970Abstract The effects of aurovertin and oligomycin on the rates of oxidative phosphorylation and arsenate-stimulated respiration have been studied over a wide range of concentrations. It has been found that both arsenate and phosphate can react with an energy-rich intermediate of oxidative phosphorylation even when reaction with ADP is prevented by ...

Biochemistry and Cell Biology, 1995
Neurofilament proteins (NFPs) are highly phosphorylated molecules in the axonal compartment of the adult nervous system. The phosphorylation of NFP is considered an important determinant of filament caliber, plasticity, and stability. This process reflects the function of NFs during the lifetime of a neuron from differentiation in the embryo through ...

Photosynthetic phosphorylation
Photosynthesis Research, 1995A brief history of the discovery of photosynthetic phosphorylation by chloroplasts and bacterial chromatophores is presented. Arnon early introduced the terminology of 'Cyclic' and 'Non-cyclic photophosphorylation' and 'Cyclic' and 'Non-Cyclic electron transport' to the processes observed in illuminated chloroplasts.

Phosphorylation of 19S Thyroglobulin
1988Thyroglobulin (TG), one of the largest known eukaryotic proteins (Mr 660.000, sedimentation coefficient 19S), plays a central role in thyroid hormonogenesis. TG presents several characteristics of special interest: (i) it represents the major biosynthetic product of thyroid follicular cell1; (ii) under denaturing conditions it can be dissociated into ...
