The local vertex anti-magic coloring for certain graph operations.

This work proves the local vertex anti-magic coloring of even regular circulant bipartite graphs . Let be either or , is a 1-factor. Also, we discover the local vertex anti-magic coloring for union of bipartite graphs; join graphs , where ; and the upper bound of corona product .

On alpha labeling of tensor product of paths and cycles.

In this article, we find an -valuation for disjoint union of some bipartite graphs and the tensor product of paths and even cycles.

Diversity of Glutathione S-Transferases (GSTs) in Cyanobacteria with Reference to Their Structures, Substrate Recognition and Catalytic Functions.

Glutathione S-Transferases (GSTs) comprise a diverse group of protein superfamily involved in cellular detoxification of various harmful xenobiotics and endobiotics. Cyanobacteria, being the primordial photosynthetic prokaryotes, served as an origin for the evolution of GSTs with diversity in their structures, substrate recognition, and catalytic functions. This study analysed the diversity of GSTs in cyanobacteria for the first time.

Analysis and elucidation of phosphoenolpyruvate carboxylase in cyanobacteria.

Phosphoenolpyruvate carboxylase (PEPC) a cytosolic enzyme of higher plants is also found in bacteria and cyanobacteria. Genetic and biochemical investigations have indicated that there are several isoforms of PEPC belonging to C3; C3/C4 and C4 groups but, the evolution of PEPC in cyanobacteria is not yet understood. The present study opens up an opportunity to understand the isoforms and functions of PEPC in cyanobacteria.

Siderophore mediated uranium sequestration by marine cyanobacterium Synechococcus elongatus BDU 130911.

Four different marine cyanobacterial morphotypes were tested for their efficacy to produce siderophores in Fe minus [Fe(-)], Fe minus Uranium dosed [Fe(-)U(+)], and Fe dosed Uranium dosed [Fe(-)U(+)] media. Of the four organisms tested, Synechococcus elongatus BDU 130911 produced the highest amount of siderophore of 58μgmg(-1) dryweight. The results clearly indicate that uranium induces siderophore production in marine cyanobacteria even in the presence of iron [Fe(-)U(+)] condition.
