In silico analysis of L-asparaginase from different source organisms

Abstract: L-asparaginases are widely distributed enzymes among plants, fungi and bacteria. This enzyme catalyzes the conversion of l-asparagine to l-aspartate and ammonia and to a lesser extent the formation of l-glutamate from l-glutamine. In the present study, forty-five full-length amino acid sequences of L-asparaginases from bacteria, fungi and plants were collected and subjected to multiple sequence alignment (MSA), domain identification, discovering individual amino acid composition, and phylogenetic tree construction. MSA revealed that two glycine residues were identically found in all analyzed species, two glycine residues were also identically found in all the fungal and bacterial sources and three glycine residues were identically found in all plant and bacterial sources while no residue was identically found in plant and fungal L-asparaginases. Two major sequence clusters were constructed by phylogenetic analysis. One cluster contains eleven species of fungi, twelve species of bacteria, and one species of plant, whereas the other one contains fourteen species of plant, four species of fungi and three species bacteria. The amino acid composition result revealed that the average frequency of amino acid alanine is 10.77 percent that is very high in comparison to other amino acids in all analyzed species.

Synthetic applications of purified laccase from Pleurotus sajor caju MTCC-141

Abstract: The study is devoted to the role of laccase, purified from the liquid culture medium of the indigenous fungal strain Pleurotus sajor caju MTCC-141, in selective bioconversion of toluene derivatives into substituted benzaldehydes with high yield. Coupling reactions of 3-(3,4-dihydroxyphenyl)propionic acid with 4-aminobenzoic, 4-aminoacetophenone and 1-hexylamine proceeded at room temperature under the action of laccase to give the corresponding products with excellent yields.

Synthesis and Spectral Characterization of O,O′- Dialkyl and Alkylene Dithiophosphates of Neodymium (III)

Abstract: Neodymium (III) dithiophosphates of the type; [Nd{S2P(OR)2}Cl2.4H2O], [Nd{S2PO2G}Cl2.4H2O], [Nd{S2P(OR)2}2Cl.3H2O], [Nd{S2PO2 G}2Cl.3H2O], [Nd{S2P(OR)2}3.3H2O] and [Nd{S2PO2G}3.3H2O] [where R = ─CH2CH2 CH3or ──C6H5; G = ─C(CH3)2CH2CH(CH3)─, ─CH2C(CH 3 )2CH2─, ─C(CH3)2C(CH3)2─, ─CH2CH2CH(CH 3 ), ─CH2C(C2H5)2CH2─ and ─CH(CH 3 )CH(CH 3 )-] were prepared by the reaction of NdCl3.6H2O and ammonium dithiophosphates in distilled water. These newly synthesized compounds have been characterized by elemental analysis, TGA, UV-visible, IR, 1 H and 31 P NMR spectral studies. Coordination numbers of eight and nine are suggested for neodymium (III) in these compounds.
