(Texas A&M University. Libraries, )The mechanism of the hydrolysis of L-leucyl-p-nitroanilide by Aeromonas aminopeptidase has been investigated by a combination of pH-dependence, competitive inhibition, and chemical modification studies. The pH-dependence ...
-
(Texas A&M University. Libraries, 1980)The variations in the potentials of the sodium-selective glass-membrane and potassium-selective valinomycin-based electrodes in various concentrations of albumin were investigated. These protein solutions serve as a simple ...
-
(Texas A&M University. Libraries, 1976)The cottonseed globulins account for the majority of the protein in the mature cottonseeds. Previous attempts to purify and characterize these proteins have resulted in techniques for fractionating the globulins into two ...
-
(Texas A&M University. Libraries, 1970)An aminopeptidase was purified 470 fold from culture filtrates of Bacillus licheniformis. The enzyme behaved as a homogeneous protein when it was subjected to disc gel electrophoresis and sedimentation velocity. The zinc ...
-
(Texas A&M University. Libraries, 1976)Thirteen samples isolated by silica gel chromatography from Aspergillus ruber grown on ground peanut slurries* were subjected to analysis with a high-resolution mass spectrometer. When sufficient amounts of sample were ...
-
(Texas A&M University. Libraries, 1982)The lysis gene region of bacteriophage lambda, containing genes S, R, and Rz, was cloned into the plasmid pBH20. In the recombinant plasmid, the lysis genes are expressed under the control of the lacOP region. The lytic ...
-
(Texas A&M University. Libraries, 1982)Transferrin, the serum iron transport protein, binds two Fe('3+) ions. Fe('3+) is not bound in the absence of carbonate or a substitute synergistic anion which serves to complete the metal binding site. In this study ...
-
(Texas A&M University. Libraries, 1983)Host Liver. The effect of the growth of the Morris hepatoma 7288CTC (CTC) upon the host liver stearoyl-CoA desaturase was examined. Host liver stearoyl-CoA desaturase activity showed a significant decrease very early during ...
-
(Texas A&M University. Libraries, 1975)The nucleoside-thiophosphorylating properties of the two phosphorus-thioxy anions, thiophosphate and dithiophosphate, were investigated. The heating of monoanionic thiophosphate with the nucleosides thymidine and 2 ...
-
(Texas A&M University. Libraries, 1975)Reticulocytes are the last immature cell type in the erythrocyte maturation process. Unlike the mature erythrocyte they are able to take up iron from transferrin, the serum iron binding protein, and incorporate it into ...
-
(Texas A&M University. Libraries, 1976)Orotidine 5'-monophosphate decarboxylase has been partially purified approximately 200-fold from Escherichia coli. The molecular weight determined by gel filtration was 56,000. The enzyme exhibited biphasic kinetics. A new ...
-
(Texas A&M University. Libraries, 1977)Dipeptides were concerted to the N-acetyl-O-n-butyl derivatives and individual mass spectra were recorded. A library of more than 50 of these spectra were placed on magnetic tape. Dipeptide derivative mixtures were prepared ...
-
(2021-05-11)Tuberculosis is one of the leading causes of death by any single infectious agent worldwide. The bacterium that causes tuberculosis, Mycobacterium tuberculosis (Mtb), has evolved mechanisms to bypass host defenses, even ...
-
(Texas A&M University. Libraries, 1976)In order to determine the effects of lysosomal enzymes on muscle proteins, fragmented sarcoplasmic reticulum was obtained from rabbit longissimus muscle and incubated with cathepsin B1 for 2 hr at 25° C and 18 hr at 2° C ...
-
(Texas A&M University. Libraries, 1983)A cytosolic proteinase has been purified to near homogeniety from rat liver. The clear supernatant obtained from a rat liver homogenate was treated with DEAE-cellulose and proteinase activity eluted by batch elution between ...
-
(2021-09-02)By the year 2050, the world’s population may exceed 9.8 billion, requiring 70% more food than we currently produce. Increased frequency of droughts and floods, spread of agricultural pests and pathogens, and application ...
-
(Texas A&M University. Libraries, 1975)Regulatory studies of the two diametrically opposed metabolic processes, anabolism and catabolism, are represented respectively, in an inquiry inot pyrimidine biosynthesis, as affected by repressing metabolites in Salmonella ...
-
(Texas A&M University. Libraries, 1983)The mechanism by which insulin acts to inhibit intracellular protein degradation has been investigated in differentiating 3T3-L1 preadipocytes, Balb/c 3T3 fibroblasts, and SV40-transformed Balb/c 3T3 fibroblasts. Intracellular ...
-
(Texas A&M University. Libraries, 1976)This study proposed a generalized mechanism for the reversible binding of lysosomal enzymes to the lysosomal membrane. Native lysosomes were partially purified from rabbit liver by standard techniques of homogenization and ...
-
(Texas A&M University. Libraries, 1978)Vibrio parahaemolyticus and Yersinia enterocolitica are two recently recognized enteric pathogens. Each of these species consists of pathogenic and non-pathogenic biotypes. At the present time, there is no reliable method ...
