Effect of divalent metal ion binding on the Raman spectrum of ATP in aqueous solution
(Elsevier, 1970-01-23)
The apparent dissociation constants for the secondary H+ of HATP-3, CaHATP-1, MgHATP-1 and ZnHATP-1 were determined by studying the pH dependent frequency of a particular line in the Raman spectrum of ATP. We obtained the ...
Kinetics of the conversion of glucose to gluconic acid by Pseudomonas ovalis
(Wiley Subscription Services, Inc., A Wiley Company, 1970-03)
The concept of a “critical oxygen concentration” is conventionally considered to hold for the submerged aerobic fermentation of glucose to gluconic acid. Above the critical level the fermentation rate is supposedly independent ...
Observations on chytridiaceous parasites of phanerogams
(Springer-Verlag, 1970-06)
A hitherto unnoted species of Physoderma on the basal leaves of Juncus pelocarpus Mey. is described. The fungus produces light brown irregularlyplaced spots on the outermost leaves. The endobiotic system is composed in ...
The self-catalyzed destruction of lipoxygenase
(Elsevier, 1970-11-25)
Lipoxygenase (E.C. 1.99.2.1) from soybean catalyzes its own destruction in the presence of both substrates, oxygen and fatty acid. The apparent first order rate constant for this inactivation was 0.050 min-1 in the presence ...
Inhibition of RNA polymerase and formyltetrahydrofolate synthetase activity by 6-chloro-8-aza-9-cyclopentylpurine. Structure-activity relationships
(Elsevier, 1970-04-02)
The structural requirements for inhibition of bacterial RNA polymerase and rabbit liver formyltetrahydrofolate synthetase activity by a series of purine nucleoside analogs related to 6-chloro-8-aza-9-cyclopentylpurine (689) ...
Observations on chytridiaceous parasites of phanerogams
(Springer-Verlag, 1970-03)
A. Physoderma found parasitic on Asclepias incarnata L. is noteworthy for the behavior of its zoospores from epibiotic sporangia. These, which bore either a colorless or ochraceous salmon colored globule, apparently lacked ...
Acyl dihydroxyacetone phosphate: Precursor of alkyl ethers
(Elsevier, 1970-06-25)
1-0-Alkyl dihydroxyacetone phosphate is biosynthesized in guinea pig liver mitochondria and in rat brain microsomes by direct reaction of a long chain alcohol and acyl dihydroxyacetone phosphate. ATP and Mg++ are stimulatory ...
Effect of sialidase on blood group specificity of hog submaxillary glycoproteins
(Elsevier, 1970-07-03)
Hogs can be divided into three phenotypes A, H and In, depending on the ability of extracts of their submaxillary glands to inhibit the agglutination of human A cells with human anti-A, and human O cells with eel-anti-H ...
Further studies on Mouthpart Receptors in decapoda crustacea
(Springer-Verlag, 1970-06)
In the lobster Homarus gammarus (L.) (= Homarus vulgaris M. Ed.) three bilateral groups of proprioceptors are arranged around the mouth. These strand receptor organs, termed Mouthpart Receptors (MPRs) 1, 2 and 3, were ...
