Mobile inteins and introns are genetic elements capable of self-propagation by “homing” into host genes and occur in entire taxonomy: eubacteria, eukarya, archaea and viruses. The process of “homing” is promoted by an ...

GnRH is a decapeptide hormone, which plays a major role in the process of mammalian reproduction. It is synthesized by the hypothalamus and binds to its cognate receptor on the pituitary, to bring about the release of ...

Investigations detailed in this thesis constitue a part of continuing programme of research work undertaken in this laboratory on vitamin binding proteins. Avidin from the chicken egg white, streptavidin &om the bacterium ...

Nuclear receptors (NRs) are important transcription factors involved in the regulation of a variety of physiological processes such as embryonic development, cell differentiation and homeostasis (for review, see Mangelsdorf ...

Characterization of the polyoma virus chromosome as a circular, double-stranded, supercoiled DNA (Weil and Vinograd, 1963; Vinograd et al.,-1965) made it apparent that the DNA enzymatic machinery faces a formidable problem ...

Investigations detailed in this thesis constitute a part of the continuing programme of research undertaken in our laboratory on the riboflavin carrier protein (RCP) with partic­ular reference to identification and synthesis ...

In the aerobic cell, oxygen can be converted into a series of reactive metabolites, together called as "reactive oxygen species" (ROS). This large group include both radical and non-radical species such as superoxide anion ...
