Bacterial peptidoglycan (PG or murein) is a single, large, covalently cross-linked macromolecule and forms a mesh-like sacculus that completely encases the cytoplasmic membrane. Hence, growth of a bacterial cell is intimately coupled to expansion of murein sacculus and requires cleavage of pre-existing cross-links for incorporation of new murein material.(More)
Dihydroxy benzenes are of considerable interest because the stabilities of the molecular H-bond as well as the interaction between the pi charges of the benzene ring and the OH group[1]. The three isomers of di-hydroxy benzene namely, catechol, resorcinol, hydroquinol are taken into consideration here. Gaussian software[2] was used to carry out the studies.(More)
Ornithine delta-aminotransferase (OAT) is an important enzyme in proline biosynthetic pathway and is implicated in salt tolerance in higher plants. OAT transaminates ornithine to pyrroline 5-carboxylate, which is further catalyzed to proline by pyrroline 5-carboxylate reductase. The Vigna aconitifolia OAT cDNA, encoding a polypeptide of 48.1 kDa, was(More)
Callus cultures from salt tolerant (CSR-10) and susceptible (Swarnadhan) varieties of Oryza sativa L. were established in Murashige and Skoog’s (MS) medium containing lethal concentrations (50 mM) of rubidium chloride (RbCl) as a selective agent. While 95–100% cells were viable in callus cultures grown without RbCl, viability was 75% in 50 mM RbCl selected(More)
The aim of this study was to formulate and evaluate stavudine floating microballoons for controlled drug release. Initially, the drug-loaded low-density granular pellets were prepared with hydroxypropyl methylcellulose E5 grade and by using isopropyl alcohol as a granulating fluid. Further, the low-density granular pellets were subjected to(More)
