Studies on a Nuclease from Azotobacter agilis

Induced biochemical mutants to Azotobacter agilis.

Metabolic Studies of Azotobacter Agilis by the Use of a Mutant Deficient in Pyruvic Oxidase*

An account has been given elsewhere of the successful isolation of physiological x-ray mutants of Azotobacter agilis with genetic blocks in the substrate oxidation mechanisms (1). The present paper deals in greater detail with a mutant strain, designated A13, that was isolated as a variant unable to grow on glucose, and gives the methods used to characterize the particular deficiency responsibl...

Studies on Azotobacter Chroococcum Beij.

The study of the metabolism of Azotobacter has been generally approached from the standpoint of the r6le of this organism in the nitrogen cycle in Nature, but the fact that the ability to fix free nitrogen is regulated by the presence or absence of combined nitrogen in the medium has not been given serious attention although it is made plain in the works to be cited. Bejierink and Van Delden (1...

Structural Studies of Tomato Nuclease TBN1

Bifunctional nuclease TBN1 from Solanum lycopersicum red tomato belongs to plant nuclease I group. TBN1 is a relatively small glycoprotein and shows considerable activity in cell apoptosis, tissue differentiation and vascular system development. Therefore detailed structural study of this enzyme can lead to new ways of cancer and bacterial disease treatment. Heterologous expression of the enzym...

a head parameter survey on mazandarani dialect and its effect(s) on learning english from ca perspective (on the basis of x-bar syntax)1

there has been a gradual shift of focus from the study of rule systems, which have increasingly been regarded as impoverished, … to the study of systems of principles, which appear to occupy a much more central position in determining the character and variety of possible human languages. there is a set of absolute universals, notions and principles existing in ug which do not vary from one ...
