In the present paper five wild Pleurotus species namely P. floridanus Singer, P. pulmonarius (Fr.) Quél., P. sapidus Quél., P. cystidiosus O.K.Mill. and P. sajor-caju (Fr.) Sing., collected from different localities of North West India have been studied for the qualitative estimation of cellulose and lignin degradation enzymes through colorimetric assays. On the basis of the results obtained, t...
Aminoglycosides (Ags) are a group of antibiotics that exert their bactericidal activity primarily by inhibition of protein synthesis. Aminoglycoside (Ag) molecules bind to the bacterial 30S ribosomal subunit rendering the ribosomes unavailable for translation, which results in cell death. Although these antibiotics are and have been very useful to treat a variety of bacterial infections, in rec...
Histone modification enzymes regulate gene expression by altering the accessibility of promoters to transcription factors. We sought to determine whether the genes encoding histone modification enzymes are dysregulated in pediatric acute lymphoblastic leukemia (ALL). A real-time PCR array was designed, tested and used to profile the expression of 85 genes encoding histone modification enzymes i...
Eukaryotic genomes contain significant amounts of transposons and repetitive DNA elements, which, if transcribed, can be detrimental to the organism. Expression of these elements is suppressed by establishment of repressive chromatin modifications. In Arabidopsis thaliana, they are silenced by the siRNA-mediated transcriptional gene silencing pathway where long non-coding RNAs (lncRNAs) produce...
MODOMICS, a database devoted to the systems biology of RNA modification, has been subjected to substantial improvements. It provides comprehensive information on the chemical structure of modified nucleosides, pathways of their biosynthesis, sequences of RNAs containing these modifications and RNA-modifying enzymes. MODOMICS also provides cross-references to other databases and to literature. I...
