Abstract excerpt

Sirohaem is a cofactor of nitrite and sulfite reductases, essential for assimilation of nitrogen and sulfur. Sirohaem is synthesized from the central tetrapyrrole intermediate uroporphyrinogen III by methylation, oxidation and ferrochelation reactions. In Arabidopsis thaliana, the ferrochelation step is catalysed by sirohydrochlorin ferrochelatase (SirB), which, unlike its counterparts in bacteria, contains an...
