On the Optimization of Hydrolysis Conditions for Simultaneous Determination of Amino Acids and Amino Sugars in Marine Sediments
(SciTecnhol, 2013-07-18)
In the present work different approaches were tested for the optimization of the hydrolysis conditions for the joint determination of amino acids and amino sugars in chitin, an important structural polymer in fungi, ...
Influence of free amino acids on clavulanic acid production by Streptomyces clavuligerus in synthetic medium
(Inst Tecnologia Parana, 2006-02-01)
The effect of nitrogen source on clavulanic acid production was investigated in shake flasks. Media containing asparagine plus one of several different amino acids or a combination of two amino acids was tested. The best ...

Structural insights into selectivity and cofactor binding in snake venom l-amino acid oxidases
(2012-04-27)
l-Amino acid oxidases (LAAOs) are flavoenzymes that catalytically deaminate l-amino acids to corresponding α-keto acids with the concomitant production of ammonia (NH 3) and hydrogen peroxide (H 2O 2). Particularly, snake ...
