Human transferrins C and DChi: An amino acid difference
A single peptide difference has been found in tryptic digests of human transferrins C and DChi. The peptide isolated from Tf C was shown to have the sequence Asp-Ser-Ala-His-Gly-Phe-Leu-Lys. The corresponding pep...

Transferrin DChi: The amino acid substitution
A peptide difference has been found in the neutral-band (pH 6.4) regions of tryptic digests of human transferrins C and DChi. The peptide has the composition Asp-Ser-Ala-Arg. Therefore, this peptide is proposed a...

Cloning and the nucleotide sequence of the genes for Escherichia coli ribosomal proteins L28 (rpmB) and L33 (rmpG)
The specialized transducing bacteriophage λdpyrE DNA was used as a source of DNA to clone two ribosomal protein genes rpmB (L28) and rpmG (L33) on the cloning vehicle pACYC184. Using one of these plasmids, the nu...

The lethal effect of a plasmid resulting from transcriptional readthrough of rplJ from the rplKA operon in Escherichia coli
A high-copy plasmid, pGA217, which carries a deletion (lacking the carboxy-terminal 20 amino acids) of the structural gene for ribosomal protein L10 (rplJ) is lethal to the cell in the absence of the gene (rplL) ...

Na+ and Ca2+ Fluxes and Differentiation of Transformed Cells
Alterations in cation fluxes across the plasma membrane appear to play a central role in the regulation of cellular growth and differentiation [1,2,4,6–8,17,19]. Oocyte maturation is stimulated by Ca2+ release in...

Amphotericin B enhances efficiency of DNA-mediated gene transfer in mammalian cells
Using plasmids containing the genes for thymidine kinase (tk) and neomycin resistance (neo), we have shown that DNA-mediated genotypic transformation of L and Chinese hamster ovary (CHO) cells is increased sev...

Both TATA box and upstream regions are required for the nopaline synthase promoter activity in transformed tobacco cells
Using a promoter expression vector system based on the tumor-inducing (Ti) plasmid of Agrobacterium tumefaciens, we have studied the molecular structure of the nopaline synthase (nos) promoter which is active con...

Three distinct regulatory elements comprise the upstream promoter region of the nopaline synthase gene
Fine deletion mutants were generated in the upstream control region of the nopaline synthase (nos) promoter to define the position and role of upstream regulatory elements. The results indicated that the 8 bp seq...
