Crystalline structure of sarcoplasmic reticulum from scallop
نویسندگان
چکیده
Negatively stained sarcoplasmic reticulum from the scallop Placopecten magellanicus presented a variety of crystalline forms, the most common being tubular structures. These were characterized by paired rows of morphological units, spaced at approximately 120 A, running diagonally across the tubules. The orthogonal unit cell (120 X 55 A) contained two units, related by a twofold axis, which probably represented the part of the Ca2+-ATPase molecule projecting from the outer surface of the membrane.

Effect of Ca2+ on the dimeric structure of scallop sarcoplasmic reticulum
Scallop sarcoplasmic reticulum (SR), visualized in situ by freeze-fracture and deep-etching, is characterized by long tubes displaying crystalline arrays of Ca2+-ATPase dimer ribbons, resembling those observed in isolated SR vesicles. The orderly arrangement of the Ca2+-ATPase molecules is well preserved in muscle bundles permeabilized with saponin. Treatment with saponin, however, is not neede...
متن کاملVariation of scallop sarcoplasmic reticulum Ca2+-ATPase activity with temperature.
Methods for preparing native scallop sarcoplasmic reticulum vesicles, largely purified membranous scallop sarcoplasmic reticulum Ca2+-ATPase, and nonionic detergent-solubilized sarcoplasmic reticulum Ca2+-ATPase are described. The effect of a range of polyoxyethylene-based detergents on the solubilized Ca2+-ATPase was tested. Decaethylene glycol dodecyl ether (C12E10) supported the highest leve...
متن کاملEffect of orthophosphate, nucleotide analogues, ADP, and phosphorylation on the cytoplasmic domains of Ca(2+)-ATPase from scallop sarcoplasmic reticulum.
The effects of orthophosphate, nucleotide analogues, ADP, and covalent phosphorylation on the tryptic fragmentation patterns of the E1 and E2 forms of scallop Ca-ATPase were examined. Sites preferentially cleaved by trypsin in the E1 form of the Ca-ATPase were detected in the nucleotide (N) and phosphorylation (P) domains, as well as the actuator (A) domain. These sites were occluded in the E2 ...
متن کاملLaser Raman characterization of conformational changes in sarcoplasmic reticulum induced by temperature, Ca2+, and Mg2+.
Laser Raman spectroscopy has been used to examine the conformations of the protein and phospholipid components of sarcoplasmic reticulum from rabbit white skeletal muscle. The phospholipid component is shown to have the conformation of fluid, liquid-crystalline lipids, even at 10 degrees C, and no breaks in the lipid conformation are observed in the range of 10-37 degrees C. Protein (predominan...

The Mg2+ + Ca2+ activated ATPase of sarcoplasmic reticulum can be visualized by negative staining with uranyl acetate or Kc-phosphotungstate in the form of 40 a diameter surface particles (I), and by freeze fracture as 85 A diameter intramembranous particles (2), which are more numerous in the cytoplasmic than in the luminal fracture face. In sarcoplasmic reticulum and in reconstituted ATPase v...
