    Sammanfattning : Many T=3 plant and insect viruses use a molecular switch in form of order/disorder of a segment of the polypeptide chain to regulate the quasi-equivalent contacts. The structure of a mutant of the T=3 capsid of bacteriophage fr confirms that this virus and other members of the Leviviridae family lack a switch mechanism. LÄS MER

    Sammanfattning : Riboflavin, also known as vitamin B2, is biosynthesized in plants, bacteria, archaea and fungi. The primary biological function of riboflavin is related to its existence as a component of the two coenzymes, flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD), which play an important role for electron transfer in energy metabolism.
