Phytochromes from Agrobacterium fabrum.
Agrobacterium fabrum is a widely used model bacterium for gene transfer from pro- to eukaryote, for genetics and metabolism. The phytochrome system of Agrobacterium, encompassing the two phytochromes Agp1 and Agp2, has provided deep insight into phytochrome action in a bacterial organism. This review summarizes recent results on phytochrome evolution, phytochrome regulation of conjugation and p...
متن کاملBacteriophytochromes control conjugation in Agrobacterium fabrum.
Bacterial conjugation, the transfer of single stranded plasmid DNA from donor to recipient cell, is mediated through the type IV secretion system. We performed conjugation assays using a transmissible artificial plasmid as reporter. With this assay, conjugation in Agrobacterium fabrum was modulated by the phytochromes Agp1 and Agp2, photoreceptors that are most sensitive in the red region of vi...
متن کاملRegulation of bile acid synthesis. IV. Interrelationship between cholesterol and bile acid biosynthesis pathways.
Under most experimental conditions, the activities of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA reductase) and cholesterol 7 alpha-hydroxylase, change together in parallel directions. It has been suggested that newly synthesized cholesterol may be the preferred substrate for cholesterol 7 alpha-hydroxylase, which may account for the observed synchronous behavior of the two enzymes. To test...
متن کاملThe biosynthesis of chlorogenic acid and related conjugates of the hydroxycinnamic acids. Chromatographic separation and characterization.
The widespread occurrence in plant tissues of conjugates with quinic acid1 and with glucose of p-coumaric acid., caffeic acid, and ferulic acid (Fig. 1) is well established (2-6). Many of these compounds occur as only trace components in extremely complex mixtures of phenolic substances. Uncertainty exists as to the exact chemical structure of most of them, and relatively little is known about ...
متن کاملAmino Acid Biosynthesis Pathways in Diatoms
Amino acids are not only building blocks for proteins but serve as precursors for the synthesis of many metabolites with multiple functions in growth and other biological processes of a living organism. The biosynthesis of amino acids is tightly connected with central carbon, nitrogen and sulfur metabolism. Recent publication of genome sequences for two diatoms Thalassiosira pseudonana and Phae...
