HemZ is essential for heme biosynthesis in Mycobacterium tuberculosis.
Parish T, Schaeffer M, Roberts G, Duncan K. Parish T, et al. Tuberculosis (Edinb). 2005 May;85(3):197-204. doi: 10.1016/j.tube.2005.01.002. Tuberculosis (Edinb). 2005. PMID: 15850757
We were able to obtain hemZ mutants by supplementation with hemin but not with protoporphyrin IX or hemoglobin confirming that this gene does have a role in heme biosynthesis and that M. tuberculosis can transport hemin intracelullarly. The hemin auxotroph required …

Transcriptional control of Bacillus subtilis hemN and hemZ.
Homuth G, Rompf A, Schumann W, Jahn D. Homuth G, et al. J Bacteriol. 1999 Oct;181(19):5922-9. doi: 10.1128/JB.181.19.5922-5929.1999. J Bacteriol. 1999. PMID: 10498703 Free PMC article.
A redox regulation cascade proceeding from an unknown sensor via resDE, through fnr and ywiD to hemN/hemZ, is suggested for the observed coregulation of heme biosynthesis and the anaerobic respiratory energy metabolism. Finally, only hemZ was found to be five …

Respiration capacity of the fermenting bacterium Lactococcus lactis and its positive effects on growth and survival.
Duwat P, Sourice S, Cesselin B, Lamberet G, Vido K, Gaudu P, Le Loir Y, Violet F, Loubière P, Gruss A. Duwat P, et al. J Bacteriol. 2001 Aug;183(15):4509-16. doi: 10.1128/JB.183.15.4509-4516.2001. J Bacteriol. 2001. PMID: 11443085 Free PMC article.
For the facultative anaerobe Lactococcus lactis, oxygen has negative effects on both growth and survival. We show here that oxygen can be beneficial to L. lactis if heme is present during aerated growth. The growth period is extended and long-term survival is markedly impr …

Metabolic engineering of cobalamin (vitamin B12) production in Bacillus megaterium.
Biedendieck R, Malten M, Barg H, Bunk B, Martens JH, Deery E, Leech H, Warren MJ, Jahn D. Biedendieck R, et al. Microb Biotechnol. 2010 Jan;3(1):24-37. doi: 10.1111/j.1751-7915.2009.00125.x. Epub 2009 Jun 10. Microb Biotechnol. 2010. PMID: 21255303 Free PMC article.
Plasmid and genome-based overexpression of genes involved in vitamin B(12) biosynthesis, including cbiX, sirA, modified hemA, the operons hemAXCDBL and cbiXJCDETLFGAcysG(A)cbiYbtuR, and the regulatory gene fnr, significantly increased cobalamin production. To reduce flux along th …

Mutations in cytochrome assembly and periplasmic redox pathways in Bordetella pertussis.
Feissner RE, Beckett CS, Loughman JA, Kranz RG. Feissner RE, et al. J Bacteriol. 2005 Jun;187(12):3941-9. doi: 10.1128/JB.187.12.3941-3949.2005. J Bacteriol. 2005. PMID: 15937156 Free PMC article.
Nine mutants were still able to synthesize c-type cytochromes and possessed insertions in the genes for cytochrome c oxidase subunits (ctaC, -D, and -E), heme a biosynthesis (ctaB), assembly of cytochrome c oxidase (sco2), or ferrochelatase (hemZ). ...

Regulation of Pseudomonas aeruginosa hemF and hemN by the dual action of the redox response regulators Anr and Dnr.
Rompf A, Hungerer C, Hoffmann T, Lindenmeyer M, Römling U, Gross U, Doss MO, Arai H, Igarashi Y, Jahn D. Rompf A, et al. Mol Microbiol. 1998 Aug;29(4):985-97. doi: 10.1046/j.1365-2958.1998.00980.x. Mol Microbiol. 1998. PMID: 9767567 Free article.
The oxidative decarboxylation of coproporphyrinogen III catalysed by an oxygen-dependent oxidase (HemF) and an oxygen-independent dehydrogenase (HemN) is one of the key regulatory points of haem biosynthesis in Pseudomonas aeruginosa. To investigate the oxygen-dependent re …

Regulation of hem gene expression in Rhodobacter capsulatus by redox and photosystem regulators RegA, CrtJ, FnrL, and AerR.
Smart JL, Willett JW, Bauer CE. Smart JL, et al. J Mol Biol. 2004 Sep 24;342(4):1171-86. doi: 10.1016/j.jmb.2004.08.007. J Mol Biol. 2004. PMID: 15351643
Biosynthetic pathways for heme and chlorophyll share common intermediates from 5-aminolevulinic acid through protoporphyrin IX. To obtain a better understanding of how photosynthetic organisms coordinate heme and chlorophyll biosynthesis, we have undertaken detailed …
