Glutamyl-tRNA reductase activity in Bacillus subtilis is dependent on the hemA gene product
The Bacillus subtilis hemAXCDBL operon encodes enzymes for the synthesis of 5-aminolaevulinic acid via the C5 pathway (hemA and hemL) and uroporphyrinogen III (hemB, hemC and hemD). B. subtilis HemA protein (molecular mass 50 kDa) was overexpressed in hemA mutants of both Escherichia coli and B. subtilis. A mutant B. subtilis HemA protein with a Cys to Tyr change at position 105 was also overexpre
