The chloride cell of Cyprinodon variegatus: cytochemical studies on a cell specialized for electrolyte transport
Cells specialized for high levels of electrolyte transport characteristically possess amplified plasmalemmas which effectively increase the exposure of the cell's surface to extracellular spaces. Of particular interest is ...
Studies on trehalose phosphate synthetase in Mycobacterium smegmatis
The biosynthesis of trehalose phosphate occurs by two reactions which utilize different sugar nucleotides, UDP-glucose or GDP-glucose. Cell free extracts of several mycobacteria catalyzed the synthesis of trehalose phosphate ...
Localization of trehalose synthesis and degradation in Ascaris
Tissues of Ascaris lumbricoides (variety suum), the large round worm of pigs, contain trehalose, a disaccharide composed of two molecules of glucose. Minces of various Ascaris tissues were incubated with C14glucose to ...
CONSTRUCTION AND CHARACTERIZATION OF ESCHERICHIA COLI PLASMIDS USEFUL IN THE MANIPULATION OF DNA
The restriction endonuclease MboII recognizes a nonpalindromic, pentanucleotide DNA sequence and cleaves both strands of the DNA eight bases downstream, leaving a single 3' protruding base. MboII is one of a group of ...
Arginase activity in mollusks
A survey of sixty-two mollusks was made for arginase activity, The enzyme was found to be present in all terrestrial forms examined, while the distribution in fresh water and marine mollusks was random. When arginase is ...
The molecular mechanism of biological membrane fusion in the yeast Saccharomyces cerevisiae
This work is focused on elucidating the molecular mechanism of biological membrane fusion using S.cerevisiae as a model system. Membrane fusion is vital for the survival of all eukaryotes, yet many aspects still remain ...
