Amino acid substitution and chemical characterization of a Japanese variant of carbonic anhydrase I: CA I Hiroshima-1 (86 Asp → Gly)
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1981-06)
An electrophoretic variant of red cell carbonic anhydrase I, designated CA I Hiroshima-1, has been observed in 12 apparently unrelated individuals during a survey of 13,019 individuals from the cities of Hiroshima and ...
Role of gangliosides in gonadotropin and cholera enterotoxin stimulated steroidogenesis in isolated rat ovarian cells
(Elsevier, 1978-07-28)
Ovarian cells isolated from 26 day old rats responded to hCG (10 ng/ml) and cholera enterotoxin (100 ng/ml) with a forty-five to fifty-fold increase in progesterone production. Both cholera enterotoxin and hCG-stimulated ...
A comparison of the responses of two tropical specialist herbivores to host plant patch size
(Springer-Verlag, 1986-03)
The effects of host plant patch size on the abundances of two specialist herbivores (the chrysomelid beetle, Acalymma innubum and the pentatomid bug, Piezosternum subulatum ) were investigated in a natural forest community ...
Immunochemical studies on the metabolism of nitrosamines by ethanol-inducible cytochrome P-450
(Elsevier, 1985-04-30)
The ethanol-induced rabbit liver microsomal cytochrome P-450, P-450LM3a, has been shown previously to efficiently catalyze the demethylation of N-nitrosodimethylamine (NDMA) with a Km of 2.9 mM. Since the predominant Km ...
Thermal adjustments in cardiac and skeletal muscles of lizards
(Springer-Verlag, 1969-03)
1. Isometric twitch tension development was measured over a wide range of temperatures in skeletal and cardiac (ventricular) muscles from diverse Australian lizards representing several families and including both diurnal ...
Cysteine 265 Is in the Active Site of, But Is Not Essential for Catalysis by tRNA-Guanine Transglycosylase (TGT) from Escherichia coli
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1997-01)
Site-directed mutagenesis and X-ray absorption spectroscopy studies have previously shown that the tRNA-guanine transglycosylase (TGT) from Escherichia coli is a zinc metalloprotein and identified the enzymic ligands to ...
Optimal foraging and fitness in Columbian ground squirrels
(Springer-Verlag, 1990-01)
Optimal diets were determined for each of 109 individual Columbian ground squirrels ( Spermophilus columbianus ) at two sites in northwestern Montana. Body mass, daily activity time, and vegetation consumption rates for ...
