ProFace: a server for the analysis of the physicochemical features of protein-protein interfaces
(BIOMED CENTRA, 2006-06-07)Molecular recognition is all pervasive in biology. Protein molecules are involved in enzyme regulation, immune response, signal transduction, oligomer assembly, etc. Delineation of physical and chemical features of the ... -
Encapsulation of pineapple micro shoots in alginate beads for temporary storage
(CURRENT SCIENCE ASSN, 2005-03-25)Micro shoots developed from the meristematic basal portion of the innermost leaves of pineapple [Ananus comosus (L.) Merr] were encapsulated in alginate beads for short-term storage as a prelude to the transformation ... -
Domain analysis of a groundnut calcium-dependent protein kinase - Nuclear localization sequence in the junction domain is coupled with nonconsensus calcium binding domains
(AMER SOC BIOCHEMISTRY MOLECULAR BIOLOGY, 2006-04-14)The signature of calcium-dependent protein kinases (CDPKs) is a C-terminal calmodulin-like domain (CaMLD) with four consensus calcium-binding sites. A junction domain (JD) joins the kinase with CaMLD and interacts with ... -
Biphasic kinetics of the colchicine-tubulin interaction: Role of amino acids surrounding the a ring of bound colchicine molecule
(AMER CHEMICAL SOC, 2005-08-02)Isotypes of vertebrate tubulin have variable amino acid sequences, which are clustered at their C-terminal ends. Isotypes bind colchicine at different on-rates and affinity constants. The kinetics of colchicine binding to ... -
The genome of the protist parasite Entamoeba histolytica
(NATURE PUBLISHING GROUP, 2005-02-24)Entamoeba histolytica is an intestinal parasite and the causative agent of amoebiasis, which is a significant source of morbidity and mortality in developing countries(1). Here we present the genome of E. histolytica, which ... -
Compositional transitions between Oryza sativa and Arabidopsis thaliana genes are linked to the functional change of encoded proteins
(ELSEVIER SCIENCE, 2006-02)Compositional transition was previously reported between homologous pairs of Oryza sativa and Arabidopsis thaliana. We analysed 2041 homologous gene pairs of O. sativa and A. thaliana and found that the genes that underwent ... -
The bacteriophage lambda DNA replication protein P inhibits the oriC DNA- and ATP-binding functions of the DNA replication initiator protein DnaA of Escherichia coli
(SPRINGER SINGAPORE PTE LTD, 2005-01-31)Under the condition of expression of ?, P protein at lethal level, the oriC DNA-binding activity is significantly affected in wild-type E. coli but not in the rpl mutant. In purified system, the 2, P protein inhibits the ... -
The mutation that makes Escherichia coli resistant to λ P gene-mediated host lethality is located within the DNA initiator gene dnaA of the bacterium
(SPRINGER SINGAPORE PTE LTD, 2005-01-31)Earlier, we reported that the bacteriophage lambda P gene product is lethal to Escherichia coli, and the E. coli rpl mutants are resistant to this lambda P gene-mediated lethality. In this paper, we show that under the ... -
Information transfer and non-locality for a tripartite entanglement using dynamics
(ELSEVIER SCIENCE BV, 2004-12-13)Without any classical channels, quantum information can be transferred using an entangled tripartite system with nonorthogonal states. We give a specific dynamical model for the preparation of such an entangled tripartite ... -
Testing quantum statistics with particles in distinguishable states
