(ELSEVIER, 2005-11)To reveal the factors influencing architecture of protein-coding genes in staphylococcal phages, relative synonymous codon usage variation has been investigated in 920 protein-coding genes of 16 staphylococcal phages. As ... -
An expeditious approach to Knoevenagel condensation of Meldrum's acid on neutral alumina using microwave irradiation
(BENTHAM SCIENCE PUBL LTD, 2006-11-01)Application of microwave irradiation to Meldrum's acid and aryl aldehydes, both adsorbed on neutral alumina, furnished efficiently the corresponding Knoevenagel condensation products remarkably fast. -
Comparative analysis of the base composition and codon usages in fourteen mycobacteriophage genomes
(ADENINE PRESS, 2005-08)To study the possible codon usage and base composition variation in the bacteriophages, fourteen mycobacteriophages were used as a model system here and both the parameters in all these phages and their plating bacteria, ... -
Magnetic field effect on photoinduced electron transfer between dibenzo[a,c]phenazine and different amines in acetonitrile - water mixture
(AMER CHEMICAL SOC,, 2007-02-08)Unlike the simple phenazine (PZ) molecule, one of its derivatives, dibenzo[a,c]phenazine (DBPZ) forms a charge-transfer complex in the triplet state ((ECT)-E-3) with different amines, e.g., N,N-dimethylaniline (DMA), ... -
Factors influencing the synonymous codon and amino acid usage bias in AT-rich Pseudomonas aeruginosa phage PhiKZ
(BLACKWELL, 2005-09)To reveal how the AT-rich genome of bacteriophage PhiKZ has been shaped in order to carry out its growth in the GC-rich host Pseudomonas aeruginosa, synonymous codon and amino acid usage bias of PhiKZ was investigated and ... -
Cyclic AMP-dependent functional forms of cyclic AMP receptor protein from Vibrio cholerae
(ELSEVIER SCIENCE INC, 2006-03-01)The cyclic AMP receptor protein (CRP) from Escherichia coli, involved in the transcriptional regulation of a number of genes and operons, works by binding to specific sites upstream of promoters. CRP also binds cyclic AMP ... -
Stimulation of Mg2+-independent form of Ca2+-ATPase by a low molecular mass protein purified from goat testes cytosol
(ELSEVIER SCIENCE INC, 2007-01-01)A low molecular mass protein purified from goat (Capra hircus) testes cytosol following gel filtration and anion exchange chromatographic separation stimulates Mg2+-independent Ca2+-ATPase activity without any significant ... -
310-Helix adjoining α-helix and β-strand: Sequence and structural features and their conservation
(WILEY-BLACKWELL, 2005-06-15)Does the amino acid use at the terminal positions of an α-helix become altered depending on the context-more specifically, when there is an adjoining 310-helix, and can a single helical cylinder encompass the resultant ... -
Hydration of protein-protein interfaces
(WILEY-BLACKWELL, 2005-07-01)We present an analysis of the water molecules immobilized at the protein-protein interfaces of 115 homodimeric proteins and 46 protein-protein complexes, and compare them with 173 large crystal packing interfaces representing ... -
Interresidue contacts in proteins and protein-protein interfaces and their use in characterizing the homodimeric interface
(AMER CHEMICAL SOC, 2005-09)The environment of amino acid residues in protein tertiary structures and three types of interfaces formed by protein-protein association-in complexes, homodimers, and crystal lattices of monomeric proteins-has been analyzed ... -
