Phosphoenolpyruvate Carboxykinase (GTP): Characterization of the Human PCK1 Gene and Localization Distal to MODY on Chromosome 20
(Elsevier, 1993-06)
The human PCK1 gene encoding phosphoenolpyruvate carboxykinase (GTP) (PEPCK) was isolated and sequenced. There is 91% amino acid sequence identity (567/622 residues) between the human and the rat proteins, with conservation ...
African bees in the Americas: Insights from biogeography and genetics
(Elsevier, 1991-01)
The spread of African honey bees in South and Central America is one of the most remarkable and certainly among the most highly publicized instances of biological invasion. Their aggressive nest defense has led to numerous ...
Embryonic regulation of histone ubiquitination the sea urchin
(Wiley Subscription Services, Inc., A Wiley Company, 1995)
We have used quantitative 2-D protein electrophoresis and immunoprecipitation to study the patterns of histone ubiquitination at 10 h and 36 h of embryonic development in Strongylocentrotus purpuratus. Variants csH2A, ΑH2A, ...
New mannose-specific lectins from garlic (Allium sativum) and ramsons (Allium ursinum) bulbs
(Elsevier, 1992-05-22)
Two new mannose-binding lectins were isolated from garlic (Allium sativum, ASA) and ramsons (Allium ursinum, AUA) bulbs, of the family Alliaceae, by affinity chromatography on immobilized mannose. The carbohydrate-binding ...
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 ...
Substitution of D-Trp 32 in NPY Destabilizes the Binding Transition State to the Y1 Receptor Site in SK-N-MC Cell Membranes
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1997-04)
The retention rate of the spin label 3-isothiocyanto methyl-2,2,5,5-tetramethyl-1-pyrrolidinyl oxyl spin label (proxyl) attached to the porcine N-acetyl-NPY peptide and the porcine N-acetyl-D-Trp 32 -NPY peptide at Lys 4 ...
Genetic structure of five susceptibility gene regions for coronary artery disease: disequilibria within and among regions
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1998-09)
We analyzed two-locus disequilibria for 16 polymorphic loci of seven susceptibility genes for coronary artery disease located in five chromosomal regions distributed across four chromosomes. Included were the genes coding ...
Intragenic complementation between Escherichia coli trp repressors with different defects in the tryptophan-binding pocket
(Elsevier, 1992-08-01)
Site-directed mutagenesis of the trpR gene (encoding the trp repressor, TrpR) was used to replace Gly85 with tryptophan (Trp or W), in order to place Trp near its normal location in the -tryptophan(-W)-binding pocket. The ...
Detection of oxidative mutagens in an urban air-particulate extract: a preliminary study
(Elsevier, 1992-12)
The Ames assays strains TA98 and TA100 have been useful in characterizing complex mixtures from organic solvent extracts of particles from diesel-powered vehicles, ambient air, and other sources. In this paper we report ...
