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 ...
Novel shuttle plasmid vehicles for Escherichia-Streptococcus transgeneric cloning
(Elsevier, 1983-11)
A novel plasmid vector that is able to replicate both in Escherichia coli and in Streptococcus sanguis is described. This 9.2-kb plasmid, designated pVA856, carries Cmr, Tcr and Emr determinants that are expressed in E. ...
A cloning vector able to replicate in Escherichia coli and Streptococcus sanguis
(Elsevier, 1982-10)
A plasmid that is able to replicate in both Escherichia coli and Streptococcus sanguis has been constructed by the in vitro joining of the pACYC184 (Cmr Tcr) and pVA749 (Emr) replicons. This plasmid, designated pVA838, is ...
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 ...
Characterization of the Determinant (traB) Encoding Sex Pheromone Shutdown by the Hemolysin/Bacteriocin Plasmid pAD1 in Enterococcus faecalis
(Elsevier, 1994-03)
pAD1 is a hemolysin/bacteriocin plasmid originally identified in Enterococcus faecalis DS16. It encodes a mating response to a peptide sex pheromone, cAD1, secreted by recipient bacteria. Once pAD1 is acquired, production ...
Interaction between bacteriophage [lambda] and its Escherichia coli host
(Elsevier, 1992)
Bacteriophage [lambda] relies to a large extent on processes requiring interactions between viral- and host-encoded proteins for its lytic growth, establishment of lysogeny, and release from the prophage state. Both ...
Characterization of the Β-Methylaspartate-Α-decarboxylase (CrpG) from the Cryptophycin Biosynthetic Pathway
(WILEY-VCH Verlag, 2007-08-13)
No Abstract
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 ...
