Two routes for synthesis of phosphoenolpyruvate from C4-dicarboxylic acids in
(Elsevier, 1974-08-19)
Mutants of defective in both phosphoenolpyruvate carboxykinase and phosphoenolpyruvate synthetase are unable to use C4-dicarboxylic acids such as succinate and malate as carbon and energy sources for growth. Revertants ...
Isolation of plasma membranes from bovine corpus luteum possessing adenylate cyclase, 125I-hCG binding and Na---K-ATPase activities
(Elsevier, 1974-01-23)
Plasma membranes from bovine corpora lutea have been purified by sucrose density gradient centrifugation. The purified membranes, in addition to binding 125I-hCG, also possess hCG-stimulated adenylate cyclase and Na---K-ATPase. ...
Analysis of selection in populations observed over a sequence of consecutive generations
(Springer-Verlag, 1974-01)
A statistical model is presented for dealing with genotypic frequency data obtained from a single population observed over a run of consecutive generations. This model takes into account possible correlations that exist ...
Analysis of an acoustic pacemaker in Strecker's chorus frog, Pseudacris streckeri (Anura: Hylidae)
(Springer-Verlag, 1974-03)
1. In breeding assemblages of Pseudacris streckeri the mating call of one individual often occurs immediately after that of another. Calling by one male then becomes entrained to that of another even though their intrinsic ...
Enzymatic transfer of the acyl group from acyl dihydroyxacetone phosphate to different substrates
(Elsevier, 1974-04-08)
The acyl group of acyl dihydroxyacetone phosphate was shown to be enzymatically transferred in guinea pig liver mitochondria to various acceptors such as lysolecithin, lysophosphatidyl ethanolamine and -glycerol-3-phosphate ...
De-esterification of cholesteryl esters in human plasma [alpha]-lipoprotein (HDL) by preparations of staphylococcal alpha toxin
(Elsevier, 1974-12-23)
SummaryChemical extraction and analysis of reaction mixtures of preparations of staphylococcal alpha toxin and human plasma [alpha]-lipoprotein (HDL) indicated that the cholesteryl esters which form an integral part of the ...
Effects of calcium ions and quinolinic acid on rat kidney mitochondrial kynurenine aminotransferase
(Elsevier, 1974-09-09)
At pH 6.4, rat kidney mitochondrial kynurenine aminotransferase activity is enhanced several-fold by the addition of CaCl2, apparently because Ca++ facilitates the translocation of [alpha]-ketoglutarate, one of the substrates, ...
Horizontal compensatory eye movements in goldfish ( Carassius auratus )
(Springer-Verlag, 1974-03)
1. Horizontal eye and head movements made by freely swimming goldfish have been recorded cinematographically and analyzed frame-by-frame.
