In previous investigations imidazoleacetic acid was shown to be quantitatively converted to formylaspartic acid by a partially purified enzyme preparation obtained from Pseudomonas sp. that requires DPNH’ and oxygen (2, 3). An intermediate in this process was isolated from the incubation mixture with highly purified enzyme preparations and was characterized as N-formimino-L-aspartic acid (4). E...

Lockhart & Abraham (1956) found that two compounds which appeared to be aspartyl-lysine and aspartyl(isoleucyl)-lysine respectively were formed when bacitracin A was hydrolysed with 11 Nhydrochloric acid at 800. The aspartic acid residue in these compounds had the L-configuration and was linked to the e-amino group of L-lysine. However, both compounds carried a net positive charge at pH 7 and t...

Minute changes in pH, NaCl concentration Aspartic acid, Glutamic acid and by inference other acids affect the major pathways from acetyl Co-A. The important differences between experiments with and without buffer show the reversal of results. Glutamic acid increases O2 consumption; cholesterol of liver homogenates in media without buffer decreases QO2,. cholesterol and total lipids in media wit...

Objective . To optimize the composition of polymer coatings based on assessment duration antibacterial resistance in infected wounds laboratory animals. Materials and methods Woven vascular prostheses consisting fibrous-porous polypropylene one three types a polyvinyl-chitosan complex with addition biologically active substances were used study. All samples impregnated 1% vancomycin for 30 minu...

Abscisic acid production by Cercospora rosicola Passerini in liquid shake culture was measured with different amino acids in combination and singly as nitrogen sources and with different amounts of thiamine in the media. Production of abscisic acid was highest with aspartic acid-glutamic acid and aspartic acid-glutamic acid-serine mixtures as nitrogen sources. Single amino acids that supported ...
