A pink, adenine-requiring yeast utilized adenine, hypoxanthine, or S -adenosylmethionine (SAM), in quantities up to 3 μmoles per 100 ml of medium, as equivalent sources of purine for cell growth, but not methylthioadenosine or S -adenosylhomocystein

SummaryExperiments performed to determine the effectiveness of adsorption-elution cycles of polyoma virus purification techniques indicated that an excess of 90% of the label in purified virus preparations is associated with virus. This was corrobora

An adenine mutant of Saccharomyces cerevisiae was able to utilize S -adenosyl- l -methionine (SAM), S -adenosyl- l -homocysteine (SAH), or adenine as sources for growth and ribonucleic acid (RNA) synthesis. Exogenous SAM or SAH was degraded after ent

The ability of activated sludge to remove phosphates was studied by adding carrier-free 32 P to raw sewage and measuring incorporation of the radioactivity into the cells over a period of time. Radioisotope determinations indicated that 48% of the 32

Activated sludges obtained from the Rilling Road plant located at San Antonio, Tex., and from the Hyperion treatment plant located at Los Angeles, Calif., have the ability to remove all of the orthophosphate normally present in Tucson sewage within 3

S -Adenosylhomocysteine (SAH) hydrolase was purified 25-fold from bakers' yeast by chemical methods and column chromatography. The purified enzyme could readily synthesize SAH from adenosine and homocysteine, but could hydrolyze only negligible amoun
