The hemA and hemT genes encoding 5-aminolaevulinic acid synthase (ALAS) from the photosynthetic bacterium Rhodobacter sphaeroides, were cloned to allow high expression in Escherichia coli. Both HemA… (More)
The common precursor to all tetrapyrroles is 5-aminolevulinic acid (ALA), and in Rhodobacter sphaeroides its formation occurs via the Shemin pathway. ALA synthase activity is encoded by two… (More)
