Properties of yeast pyruvate decarboxylase and their modification by proteolytic enzymes : I. Stability of decarboxylases from wild-type and mutant strains
(Elsevier, 1968)
High concentrations of inorganic phosphate and ammonium sulfate stabilize yeast pyruvate decarboxylase to heating at 60 [deg] for long periods of time in the presence of TPP and Mg+. When heated at 60 [deg] in phosphate ...
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 ...
Development of pure culture biofilms of P. putida on solid supports
(Wiley Subscription Services, Inc., A Wiley Company, 1991-03-15)
Pseudomonas putida biofilms were developed on and biofilm accumulation rate data were obtained for the following two classes of support materials: charged surfaces and noncharged hydrophobic and hydrophilic surfaces. The ...
Etiologic role of lactic dehydrogenase virus infection in an age-dependent neuroparalytic disease in C58 mice
(Elsevier, 1980-05)
Lactic dehydrogenase virus (LDV) associated with transplantable line Ib lymphocytic leukemia in C58/Wm mice, K36 lymphocytic leukemia in AKR/J mice, and the Gardner lymphosarcoma in C3H/HeJ mice elicited a fatal neuroparalytic ...
Heterologous expression of tylosin polyketide synthase and production of a hybrid bioactive macrolide in Streptomyces venezuelae
(Springer-Verlag, 2006-02-22)
Tylosin polyketide synthase (Tyl PKS) was heterologously expressed in an engineered strain of Streptomyces venezuelae bearing a deletion of pikromycin PKS gene cluster using two compatible low-copy plasmids, each under the ...
Growth equations: A general equation and a survey of special cases
(Elsevier, 1980-04)
Although growth in its various manifestations has been studied for centuries and although there are a large number of well-established growth "laws," that work is almost entirely empirical and lacks a theoretical foundation ...
Cooperative effects of bacterial mutations affecting [lambda] N gene expression : II. Isolation and characterization of mutations in the rif region
(Elsevier, 1976-08)
We report the isolation and initial characterization of a class of mutations, Snu, that map near the rif locus on the Escherichia coli chromosome. Snu mutations inhibit the growth of phage [lambda], an effect primarily ...
Infectivity of a glucan synthesis-defective mutant of Streptococcus gordonii (Challis) in a rat endocarditis model
(Elsevier, 1993-09-15)
Streptococcus gordonii, a member of the human indigenous oral microflora, colonizes smooth tooth surfaces and contributes to dental plaque formation. Although it is not recognized as being a cariogenic pathogen, it may ...
