| Abstract |
hemA and hemM, which are 213 bp apart and divergently transcribed, were separately cloned. We found that hemA is required for 5-aminolevulinic acid (ALA) synthesis in two ALA- auxotrophs. Overexpression of hemM alone did not produce ALA. More ALA was produced by strains harboring a plasmid with both hemA and hemM than by those with hemA alone. We conclude that hemA alone is required for ALA synthesis but hemA and hemM are required for maximal ALA synthesis. |
