improved assay method for phospholipase c.a lecithin sol dispersed with deoxycholate was found to be attacked by phospholipase c in the presence of calcium ion more rapidly than were any other lecithin sols. the inorganic phosphate could be released quantitatively from the acid soluble phosphate liberated from lecithin by an excess amount of alkaline phosphatase present in phospholipase c reaction mixture. a simple and accurate assay method for phospholipase c was developed with the sol and the alkaline phosphatase.19674962285
ultraviolet irradiation of dna in vitro and in vivo produces a 3d thymine-derived product.a new thymine-derived product was separated from dna irradiated with utlraviolet light in vitro and in vivo. this compound was mistaken to be thymine homodiner (t=t) by other workers because it is chromatographically indistinguishable from t=t in most eluents. it has absorbancy maximums at 312, 312, and 300 millimicrons in neutral, ph 2, and ph 11 aqueous solutions, respectively. when it is irradiated in aqueous solution with wavelengths of 360 and 313 millimicrons its spectrum reverts to one si ...19674960673

induced rapid release and uptake of phosphate by microorganisms.cultures of bacteria and of mixed microorganisms are able to release actively a large proportion of their phosphorus to the medium in a matter of hours when kept under anoxic conditions. only phosphorus is lost, probably as orthophosphate and apparently mostly from the acid-soluble fraction of the cells. the process, which is completely reversible upon aeration, has a change in rate (for a change of 10 degrees c) of 2 to 2.5.19674959890

x-ray diffraction studies on selected bacterial cell walls.the cell walls of selected bacteria were studied by x-ray diffraction analysis to determine and characterize crystalline components. the walls were isolated by mechanical disruption and purified by enzymatic and washing procedures. the x-ray diffraction lines which appeared from the gram-positive cell walls were shown to be due to the constituent "mucopeptide" fraction. no diffraction lines could be obtained from the gram-negative bacterium studied. the results show that crystallinity is associa ...19674960150
regulation of extracellular protease production in bacillus cereus.both sporulation and protease production can be inhibited by growing bacillus cereus t in a medium containing a high concentration of a mixture of amino acids. mutants selected for the ability to sporulate in this inhibitory medium were found to produce high levels of protease in the normal and inhibitory media. comparison of the mutant and wild-type enzymes by gel electrophoresis and heat inactivation suggested that they were identical. one of the mutants proved to be a purine-requiring auxotro ...19674960917
