Recent work has shown that certain growth inhibitory purine analogues undergo anabolism to ribonucleoside 5’-phosphates (1, 2). Ribonucleoside 5’-phosphate derivatives of purine analogues that effect temporary remission of some human leukemias have been synthesized (3-6), and effects of these nucleotides on enzymatic interconversions of naturally occurring purine nucleotides have been studied (...

The successful colonization of plant growth promoting rhizobacteria (PGPR) in the rhizosphere is an initial and compulsory step in the protection of plants from soil-borne pathogens. Therefore, it is necessary to evaluate the role of root exudates in the colonization of PGPR. Banana root exudates were analyzed by high pressure liquid chromatography (HPLC) which revealed exudates contained sever...

there is a great interest in developing rapid analytical methods and provide appropriate parametersfor quantitative analysis of compounds derived from refractory pollutants. such methods are important forroutine quality control analysis of an effluent before being discharged into the environment. therefore, a rapid methodology for identification and quantification of some aliphatic acids is pro...

LTHOUGH fumarase was discovered by Einheck1 in 1919 and has subsequently been found to have a wide biological distribution, there are no reports to our knowledge of its activity in separated human beukocvtes. Fitmarase is one of the essential enzymes that catalyze the oxidation of carbohydrates, fatty acids and some amino acids via the citric acid cycle. Specifically, fumarase mediates the esta...
