PTC-1: A homologue of TFL1/CEN involved in the control of shoot architecture in Beta palonga
(CURRENT SCIENCE ASSOC, 2008-01-10)A terminal flower mutant phenotype of Beta palonga, a leafy vegetable, isolated earlier has been characterized. Micromorphological and histological study of the normal and mutant phenotype reveals physiognomic similarity ... -
Enhanced stability of cis Pro-Pro peptide bond in Pro-Pro-Phe sequence motif
(ELSEVIER, 2007-09-18)dentification of sequence motifs that favor cis peptide bonds in proteins is important for understanding and designing proteins containing turns mediated by cis peptide conformations. From H-1 NMR solution studies on short ... -
Role of ICT in Digital Information Era with Special Reference to Research Library
(IASLIC, 2007)This will be Available Shortly... -
A cDNA-AFLP approach to look for differentially expressed gene fragments in dioecious pointed gourd (Trichosanthes dioica Roxb.) for understanding sex expression
(CURRENT SCIENCE ASSO, 2008-02-10)Transcript profiling of unopened male and female floral buds of pointed gourd (Trichosanthes dioica Roxb.), a dioecious cucurbit, at uniform developmental stage was done through eDNA-AFLP to look for the differentially ... -
Detection of antistaphylococcal and toxic compounds by biological assay systems developed with a reporter Staphylococcus aureus strain harboring a heat inducible promoter - lacZ transcriptional fusion
(SPRINGER SINGAPORE PTE LTD, 2007-11-30)Previously it was reported that promoter of groES-groEL operon of Staphylococcus aureus is induced by various cellwall active antibiotics. In order to exploit the above promoter for identifying novel antistaphylococcal ... -
Purification and characterization of repressor of temperate S-aureus phage phi 11(M-T-2007)
(SPRINGER SINGAPORE PTE LTD, 2007-09-30)To gain insight into the structure and function of repressor proteins of bacteriophages of gram-positive bacteria, repressor of temperate Staphylococcus aureus phage 11 was undertaken as a model system here and purified ... -
Nature of selective constraints on synonymous codon usage of rice differs in GC-poor and GC-rich genes
(ELSEVIER, 2007-10-01)Synonymous codon usage and cellular tRNA abundance are thought to be co-evolved in optimizing translational efficiencies in highly expressed genes. Here in this communication by taking the advantage of publicly available ... -
Isotropic to nematic phase transition in F-actin
(Elsevier B.V, 2007)Like a few other rod-like and semi-rigid polyelectrolytes, filamentous actin (F-actin) shows, respectively, an isotropic to nematic (I-N) phase transition and an aggregation to a hexagonal liquid crystal followed by ... -
Repressor of temperate mycobacteriophage LI harbors a stable C-terminal domain and binds to different asymmetric operator DNAs with variable affinity (M-T-2007)
(BIOMED CENTRAL LTD, 2007-06-28)Background: Lysogenic mode of life cycle of a temperate bacteriophage is generally maintained by a protein called 'repressor'. Repressor proteins of temperate lambdoid phages bind to a few symmetric operator DNAs in order ... -
Probing the antiprotease activity of lambda CIII, an inhibitor of the Escherichia coli metalloprotease HflB (FtsH)
(AMER SOC MICROBIOLOGY, 2007-11)The CIII protein encoded by the temperate coliphage lambda acts as an inhibitor of the ubiquitous Escherichia coli metalloprotease HflB (FtsH). This inhibition results in the stabilization of transcription factor lambda ... -
Mycobacterium avium -induced matrix metalloproteinase-9 expression occurs in a cyclooxygenase-2-dependent manner and involves phosphorylation- and acetylation-dependent chromatin modification
(Elsevier B.V., 2007-12-01)Matrix metalloproteinases (MMPs) contribute to the matrix-degrading phenotype of mycobacterial diseases. Considering that MMPs could contribute to the mutual exacerbation of both Mycobacterium avium and HIV in coinfections, ... -
Three-dimensional models of NB-ARC domains of disease resistance proteins in tomato, arabidopsis, and flax
(ADENINE PRESS, 2008-02)Three dimensional models of NB-ARC domains in five different proteins were constructed based on the recently published crystal structure of the apoptotic protease activating factor 1, of which two are for tomato species, ... -
Synonymous codon usage in different protein secondary structural classes of human genes: Implication for increased non-randomness of GC(3) rich genes towards protein stability
(INDIAN ACAD SCIENCES, 2007-08)The relationship between the synonymous codon usage and different protein secondary structural classes were investigated using 401 Homo sapiens proteins extracted from Protein Data Bank (PDB). A simple Chi-square test was ... -
Bipolar spindle frequency and genome content are inversely regulated by the activity of two N-type kinesins in Entamoeba histolytica
(WILEY-BLACKWELL, 2008-06)Bipolar microtubular spindles are seen infrequently in Entamoeba histolytica trophozoites while monopolar or radial microtubular assemblies are common. Additionally, heterogeneity in nuclear DNA content and multi-nucleation ... -
Entamoeba histolytica encodes unique formins, a subset of which regulates DNA content and cell division
(AMER SOC MICROBIOLOGY, 2008-06)The formin family of proteins mediates dynamic changes in actin assembly in eukaryotes, and therefore it is important to understand the function of these proteins in Entamoeba histolytica, where actin forms the major ... -
Direct extracellular interaction between the early secreted antigen ESAT-6 of Mycobacterium tuberculosis and TLR2 inhibits TLR signaling in macrophages
(NATURE PUBLISHING GROUP, 2007-06-02)Expression of early secreted antigenic target protein 6 (ESAT-6) by Mycobacterium tuberculosis is associated with lower innate immune responses to infection. Here we show that ESAT-6 inhibited activation of transcription ... -
