dip Ramayan actor Dipika Chikhlia says she would like to play Kaikeyi, Sunil Lahiri'spick is Raavan By Published On :: Sun, 10 May 2020 12:22:51 GMT Actor Dipika Chikhlia, who was seen playing the role of Sita in Ramayan, was introduced to an unmatched popularity that has not faded even today. In an earlier interview, she had revealed how people in the villages would still refer to her as Sita and would even try touching her feet! However, given a choice today, Sita would not be the character she would like to play. In a recent conversation, Dipika revealed she had evolved as an actor, and would rather be interested to play Kaikeyi, lord Ram's stepmother who insisted her husband Dashratha to send Ram, Lakshman and Sita to an exile for 14 years. Dipika added that playing a negative career was an entirely different experience and she was fond of playing roles that let her explore herself as an artist. Actor Sunil Lahiri, who played Lakshman's character, said he'd still pick the same role, but if he had another choice, he would like to get into the shoes of Ravana as the character had many shades and would give an actor many varieties to perform. As the nationwide lock-down began, Doordarshan started re-airing some of its most popular TV shows, Ramayan being the first one. On April 16, it became the world's most watched TV show, with 7.7 crore viewers. Full Article

dip Structure of the 4-hydroxy-tetrahydrodipicolinate synthase from the thermoacidophilic methanotroph Methylacidiphilum fumariolicum SolV and the phylogeny of the aminotransferase pathway By scripts.iucr.org Published On :: 2020-04-28 The enzyme 4-hydroxy-tetrahydrodipicolinate synthase (DapA) is involved in the production of lysine and precursor molecules for peptidoglycan synthesis. In a multistep reaction, DapA converts pyruvate and l-aspartate-4-semialdehyde to 4-hydroxy-2,3,4,5-tetrahydrodipicolinic acid. In many organisms, lysine binds allosterically to DapA, causing negative feedback, thus making the enzyme an important regulatory component of the pathway. Here, the 2.1 Å resolution crystal structure of DapA from the thermoacidophilic methanotroph Methylacidiphilum fumariolicum SolV is reported. The enzyme crystallized as a contaminant of a protein preparation from native biomass. Genome analysis reveals that M. fumariolicum SolV utilizes the recently discovered aminotransferase pathway for lysine biosynthesis. Phylogenetic analyses of the genes involved in this pathway shed new light on the distribution of this pathway across the three domains of life. Full Article text

The imidazolidine ring is oriented at dihedral angles of 79.10 (5) and 82.61 (5)° with respect to the phenyl rings, while the dihedral angle between the two phenyl rings is 62.06 (5)°. In the crystal, intermolecular C—HProp⋯OImdzln (Prop = prop-2-yn-1-yl and Imdzln = imidazolidine) hydrogen bonds link the molecules into infinite chains along the b-axis direction. Two weak C—HPhen⋯π interactions are also observed. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H⋯H (43.3%), H⋯C/C⋯H (37.8%) and H⋯O/O⋯H (18.0%) interactions. Hydrogen bonding and van der Waals interactions are the dominant interactions in the crystal packing. Computational chemistry indicates that the C—HProp⋯OImdzln hydrogen-bond energy in the crystal is −40.7 kJ mol−1. Density functional theory (DFT) optimized structures at the B3LYP/6–311G(d,p) level are compared with the experimentally determined molecular structure in the solid state. The HOMO–LUMO behaviour was elucidated to determine the energy gap. Full Article text
