The nucleosome is the fundamental building block of chromatin. Changes taking place at the nucleosome level are the molecular basis of chromatin transactions with various enzymes and factors. These changes are directly and indirectly regulated by chromatin modifications such as DNA methylation and histone post-translational modifications including...
DOT1L methylates histone H3 lysine 79 during transcriptional elongation and is stimulated by ubiquitylation of histone H2B lysine 120 (H2BK120ub) in a classical trans-histone crosstalk pathway. Aberrant genomic localization of DOT1L is implicated in mixed lineage leukemia (MLL)-rearranged leukemias, an aggressive subset of leukemias that lacks effe...
Background/ Aims
Nucleosomes impose physical barriers on enzymes translocating along nucleosomal DNA such as RNA Polymerase II (Pol II). As such, nucleosome dynamics is a molecular basis of gene regulation. We investigated nucleosome dynamics during transcription elongation by Pol II with three specific aims to 1) elucidate how lysine acetylation a...
The nucleosome is the basic packing unit of the eukaryotic genome. Dynamic interactions between DNA and histones in the nucleosome are the molecular basis of gene accessibility regulation that governs the kinetics of various DNA-templated processes such as transcription elongation by RNA Polymerase II (Pol II). On the basis of single-molecule FRET...
Dehydroquinase (3-dehydroquinate dehydratase, DHQD, EC 4.2.1.10) catalyzes the conversion of dehydroquinate to dehydroshikimate. DHQD from Acinetobacter baumannii (AbDHQD) was cloned, expressed and purified to homogeneity. The binding studies showed that two compounds quinic acid and citrazinic acid bound to AbDHQD at micromolar concentrations. AbD...
Peptidoglycan recognition proteins belong to a broad family of innate immunity molecules. Mammals have four types of peptidoglycan recognition proteins designated as PGRP-S, PGRP-Iα, PGRP-Iβ and PGRP-L. PGRP-S is expressed in the granular polymorphonuclear leucocytes, PGRP-Iα is secreted from liver into blood and PGRP-Iβ, and PGRP-L are expressed i...
The commercial micropropagation grapples with the major problem of poor survivality of regenerated plants upon ex vitro transfer. The basic cause for its poor survivality is believed to be the reduced vigor of the plants during the culture period. The present work describes a RGB based image analysis method to estimate the chlorophyll content of mi...
A method has been developed for rapid and non invasive determination of chlorophyll content of leaves of micropropagated potato
plants using RGB based image analysis. Among the trichomatic colors, R and G negatively correlated with the chlorophyll content,
while a positive correlation was observed with B chromate. Compared to mean brightness value,...
