(Texas A&M University. Libraries, 1977)An in vitro method is described which was designed to study the activation by copper of lysyl oxidase in aortas from 10 day copper deficient chicks. The optimum conditions for the activation by copper of lysyl oxidase were ...
-
(Texas A&M University. Libraries, 1988)The transcriptional activity of the mouse mammary tumor virus (MMTV) promoter is positively regulated by the action of glucocorticoid hormones. This action is thought to be mediated, at least in part, by the binding of the ...
-
(Texas A&M University. Libraries, 1986)Bacteriophage Mu dl(lac,Ap[superscript r]), a transposable element, was used to inactivate the pyrB gene by insertion. Derivatives of these pyrimidine auxotrophs were used to select the pyrB gene cloned pBR322. Three ...
-
(Texas A&M University. Libraries, 1991)The Escherichia coli Rep protein has DNA-dependent ATPase activity and unwinds duplex DNA with an apparent 3' to 5' directionality. Biochemical and biophysical aspects of the Rep helicase-DNA interactions were examined in ...
-
(Texas A&M University. Libraries, 1987)The major objective of this study was to characterize the regions of poly(A) signals, which in addition to the AAUAAA are sufficient for accurate and efficient polyadenylation. In addition, this study was designed to test ...
-
(Texas A&M University. Libraries, 1994)The Autographa californica nuclear polyhedrosis virus (AcNPV) expresses several immediate-early genes in infected cells. One of these, ie2 (formerly called IEN), was mapped by its ability to augment IE1 - mediated ...
-
(Texas A&M University. Libraries, 1987)As the plant proceeds through development from a seed to a photosynthetically competent organism, plastids of leaf tissue differentiate into chloroplasts. This process is due to the coordinated expression of nuclear and ...
-
(Texas A&M University. Libraries, 1987)The ATCase from Escherichia coli has been the subject of extensive physical, biochemical and genetic studies. The exact natures of the intrasubunit and intersubunit interactions responsible for enzymatic function are still ...
-
(Texas A&M University. Libraries, 1993)Transcription of vertebrate U6 snRNA genes by RNA polymerase III requires two sequence elements in the proximal promoter region: the PSE (proximal sequence element, found in snRNA promoters transcribed by RNA polymerase ...
-
(Texas A&M University. Libraries, 1992)
-
(Texas A&M University. Libraries, 1975)The effectiveness of a variety of protein denaturants has been determined on two proteins, [beta]-lactoglobulin A and Ribonuclease A. These proteins were chosen because they differ substantially in relative hydrophobicity. ...
-
(Texas A&M University. Libraries, 1988)We have determined the conformational stability of Ribonuclease T1, (RNase T1), and a derivative of RNase T1 with the 2 to 10 disulfide bond broken and the cysteine residues carboxymethylated, at our standard conditions ...
-
(Texas A&M University. Libraries, 1995)Site-directed mutagenesis was used to examine the contribution of buried and exposed aromatic amino acids to the spectral properties and conformational stability of ribonuclease T, (RNase T,). The side chain of Trp59 is ...
-
(Texas A&M University. Libraries, 1993)Plastid transcription activity and DNA copy number were quantified during chloroplast development in the first foliage leaf of dark-grown and illuminated barley seedlings. Plastids isolated from cells located in the basal ...
-
(Texas A&M University. Libraries, 1990)The putative domains of the large subunit of carbamoyl phosphate synthetase from Escherichia coli have been isolated and characterized for carbamoyl phosphate synthesis, ATP synthesis, and bicarbonate-dependent ATPase ...
-
(Texas A&M University. Libraries, 1968)The effect of gossypol on the enzymatic activity of crystalline trypsin, pepsin, muscle aldolase, and the activation of pepsinogen has been established in in vitro systems. Trypsin activity was completely inhibited using ...
-
(Texas A&M University. Libraries, 1980)The research described in this dissertation concerns the investigation of selected 6-mercaptopurine metallo complexes. Syntheses are developed, the compounds are screened for anti-carcinogenic activity in two in vivo ...
-
(Texas A&M University. Libraries, 1994)TCDD is a broad spectrum antiestrogen and mediates its antiestrogenic effects through the aryl hydrocarbon receptor (AhR). 176-estradiol (E2) induces the secretion of procathepsin D, a 52-kDa protein in MCF-7 human breast ...
-
(Texas A&M University. Libraries, 1973)The major objectives of this study were to determine the effects of diet cholesterol on serum apoprotein synthesis and to test the hypothesis that the synthesis of serum high density apoprotein and cholesterogenesis may ...
-
(Texas A&M University. Libraries, 1976)Resistance to the proline analogue, azetidine-2-carboxylic acid, was used as a selection technique with E. coli in order to measure the production of mutations caused by low doses of X-radiation. An improved procedure was ...
