Effectiveness factor calculations for immobilized enzyme catalysts
(Wiley Subscription Services, Inc., A Wiley Company, 1973-09)
The steady state, nonlinear diffusion equations which describe reactions in constrained enzyme solutions are of great interest in many biological and engineering applications. As in other types of nonlinear differential ...
Micro method for determination of borohydride with NAD+
(Elsevier, 1973-08)
A spectrophotometric method for the determination of borohydride is described. It involves the reduction of NAD+ to a number of isomeric forms of NADH by borohydride. In the standard assay procedure herewith presented, ...
Experimental and mathematical modeling studies of protozoan predation on bacteria
(Wiley Subscription Services, Inc., A Wiley Company, 1973-07)
The predation of bacteria by protozoan in both continuous and batch cultures was studied using experimental and modeling techniques. The predator organism was the ciliate, Tetrahymena pyriformis. The bacterium, Aerobacter ...
Evidence for the utilization of host tRNA(m5 U)methylase to modify tRNA coded by phage T4
(Elsevier, 1973-04)
Mutants of Escherichia coli defective only in the biosynthesis of 5-methyluridine (ribothymidine) in their transfer ribonucleic acid (tRNA) were employed to investigate whether phage T4 induces its own tRNA (m5U)methylase ...
Genetic variation in the carbonic anhydrase isozymes of macaque monkeys : III. Biosynthesis of carbonic anhydrases in bone marrow erythroid cells and peripheral blood reticulocytes of Macaco nemestrina
(Elsevier, 1973-09)
The carbonic anhydrase isozymes (CA I and CA II) of the pig-tailed macaque, Macaca nemestrina, have been chosen to study the regulation of enzyme levels in red blood cells. Two quantitative variants of CA I that are ideal ...
Quantitative determination of reducing sugars, oligosaccharides, and glycoproteins with [3H]borohydride
(Elsevier, 1973-09)
A very simple and direct radioactive isotope method has been described for the quantitative determination of reducing sugars. The method can be adapted to give any degree of sensitivity desired. The procedure is of general ...
The linear algebra for linked loci with mutation
(Elsevier, 1973-04)
A linear algebra is defined describing this situation: Any number of loci are linked with arbitrary linkage distribution, and each allele may mutate into the other alleles with given frequencies. Mutations at different ...
