Common NameNi-sirohydrochlorin
DescriptionNi-sirohydrochlorin is a nickel-containing tetrapyrrole belonging to the chemical class of chlorins. Its chemical structure features a central nickel ion coordinated by a macrocyclic framework composed of four pyrrole-like units, which are characteristic of porphyrin derivatives. In the biosynthetic pathway, Ni-sirohydrochlorin is synthesized through the process of nickelochelation mediated by a nickel-specific chelatase, which facilitates the incorporation of nickel into the tetrapyrrole structure. Following this chelation step, amidation occurs, resulting in the formation of Ni-sirohydrochlorin a,c-diamide (PMID:27846569 ). This compound is involved in various biochemical processes, including those related to nickel metabolism and potentially influencing enzymatic activities associated with nickel-dependent enzymes. The intricate interplay of its chemical structure and biological pathways underscores the significance of Ni-sirohydrochlorin in the context of nickel biochemistry and its potential roles in microbial and plant systems.
