Pneumoviruses: Molecular Genetics and Reverse Genetics
Pneumoviruses are responsible for significant respiratory disease in their hosts and represent a major problemfor human and animal health. Pneumoviruses are members of the family Paramyxoviridae, subfamilyPneumovirinae and the virus particles consist of a negative-sense, nonsegmented RNA genome within a helical nucleocapsid structure enveloped in a lipid membrane derived from the ho...
متن کاملTryptophan Biosynthesis and Molecular Genetics Biochemical and
Tryptophan is the one of the least abundant yet, in terms of energy, one of the most expensive to produce of the standard protein amino acids (Hrazdina and Jensen, 1992). The Iow leve1 of soluble tryptophan present in plants (1 to 15 pM) belies the importance of the amino acid and the pathway that produces it (Gilchrist and Kosuge, 1980). Animals, and some eubacteria, lack the ability to synthe...
متن کاملTaxol biosynthesis: an update.
The novel diterpenoid taxol (paclitaxel) is now well-established as a potent chemotherapeutic agent. Total synthesis of the drug is not commercially feasible and, in the foreseeable future, the supply of taxol and its synthetically useful progenitors must rely on biological methods of production. The first three steps of taxol biosynthesis have been defined and the responsible enzymes described...
متن کاملMolecular Genetics and Epidemiology of Vitiligo
Background: Vitiligo is an acquired, idiopathic, and common depigmentation disorder of the skin that affects people of all ages and both sexes equally in the worldwide. Although etiology of the disease is unknown, there are theories such as environment and genetic factors. Methods: In this article, we collected and summarized the appropriate manuscripts regarding the epidemiology and gene...
متن کاملMolecular genetics of disorders of haem biosynthesis.
Introduction Haem is synthesised in all animal cells from succinyl CoA and glycine by a sequence of reactions catalysed by eight enzymes.1 Absence of any one of these enzymes is incompatible with life because haem is an essential component of respiratory proteins. Partial deficiencies occur, however, and cause disease (table 1).12 The activity of 5-aminolaevulinate (ALA) synthase, the first and...
