(2009-03-13)Diaminopropionate ammonia lyase (DAPAL) which belongs to the class of PLP enzymes is reported only from prokaryotes. It is involved in the removal of two amino groups from its substrate, diaminopropionate, to form ammonia ... -
Identification Of Chloroquine Resistant Haplotypes Of Plasmodium Falciparum In India And Development Of New Antimalarial Combinations
(2008-10-03)Malaria afflicts 300-500 million people in the world and the mortality ranges from 1-2 million, children in Africa being the most susceptible. With a vaccine not being available against malaria and the front line drugs ... -
Manganese-Dependent Serine/Threonine/Tyrosine Kinase From Arabidopsis Thaliana : Role Of Serine And Threonine Residues In The Regulation Of Kinase Activity
(2008-10-01)Protein phosphorylation is an important post-translational modification of proteins, which can either activate or inhibit the function of a given protein. The enzymes, protein kinases and protein phosphatases catalyze the ... -
Heat Shock Protein 70 Of Plasmodium Falciparum: Proteomic Analysis Of Its Complexes And Cellular Functions
(Indian Institute Of Science, 2004-10)Hest shock protein 70 (Hsp70) class of chaperones is highly conserved and present ubiquitously in all cellular organisms They play important role in folding of nascent polypeptides and translocation of precursor proteins ... -
Study of Ca2+-Mediated Signal Transduction During Embryogenesis In Sandalwood (Santalurm Album L.) And Characterization Of An Early Development-Specific CDPK
(Indian Institute of Science, 2005-12-08)Calcium ion plays a pivotal role as second messenger during signal/response coupling in plant cells (Trewavas, 1999). Elevations of cytosolic Ca2+ occur in plants as a consequence of abiotic and biotic stresses, environmental ... -
Studies On The Molecular Mechanism Of Cytokinin Action: Involvement Of Ca2+, Protein Kinase And Concurrent Protein Synthesis In Signaling Of Cytokinin-Induced Expression Of Pathogenesis-Related Enzymes In Cucumber
(Indian Institute of Science, 2005-12-08)Phytohormones act as signals to regulate plant growth and development by modulation of gene expression in response to internal developmental cues or external environmental stimuli, such as light and pathogen infection. ... -
Functional Differentiation Of The Human Placenta : Insights From The Expression Of Two Developmentally - Regulated Genes
(Indian Institute of Science, 2005-12-08)Placenta is a transient association of the fetal and maternal tissues, that develops during pregnancy, in most viviparous animals. The evolution of placenta ensured the development of the fetus inside the womb of the mother, ... -
