Genetics of Tetrapyrrole Synthesis in Gram-Positive Bacteria

The organization and regulation of genes for tetrapyrrole synthesis were studied in low G+C Gram-positive bacteria. Clusters of genes encoding enzymes for tetrapyrrole biosynthesis were cloned from Bacillus sphaericus, Bacillus stearothermophilus, Brevibacillus brevis and Paenibacillus macerans. The structure of the hem gene clusters was compared to that of other Gram-positive bacteria. The hemEHY
