Molecular cloning of the 5-aminolevulinic acid dehydratase gene from Rhodobacter sphaeroides.
A hemB mutant of Escherichia coli was used to clone the gene encoding 5-aminolevulinic acid dehydratase from Rhodobacter sphaeroides after physiological complementation of the mutation. A 2.9-kb DNA fragment was obtained and cloned in both orientations into the unique PstI restriction site of pUC19. This recombinant plasmid encodes a protein (Mr 39,000) that is immunoreactive with antibodies ra...
متن کاملOptimization of Biomass and 5-Aminolevulinic Acid Production by Rhodobacter sphaeroides ATCC17023 via Response Surface Methodology.
Microbial 5-aminolevulinic acid (ALA) produced from wastewater is considered as potential renewable energy. However, many hurdles are needed to be overcome such as the regulation of key influencing factors on ALA yield. Biomass and ALA production by Rhodobacter sphaeroides was optimized using response surface methodology. The culturing medium was artificial volatile fatty acids wastewater. Thre...

متن کاملPorphyrin Synthesis from 5-Aminolevulinic Acid in Patients with Glioma
The molecule 5-aminolevulinic acid (5-ALA) is a substrate for a heme synthesized in cells us‐ ing succinyl CoA and glycine. Initially, 5-ALA is converted to porphobilinogen (PBG), and the metabolism progresses by the action of PBG deaminase, and its product is incorporated into the mitochondria via uroporphyrinogen and coproporphyrinogen by an enzymatic reaction and transformed into protoporphy...
