IPR000523 is a Magnesium chelatase ChlI-like, catalytic domain.
<p>This domain can be found in the magnesium chelatase ChlI subunit, the catalytic domain that binds and hydrolyses ATP. This domain contains the nucleotide binding Walker motif [[cite:PUB00097705]] and can also be found in the competence protein ComM from Haemophilus influenzae and Lon proteases from archaea.</p> <p>Magnesium-chelatase is a three-component enzyme that catalyses the insertion of Mg<sup>2+</sup>into protoporphyrin IX. This is the first unique step in the synthesis of (bacterio)chlorophyll. As a result, it is thought that Mg-chelatase has an important role in channeling intermediates into the (bacterio)chlorophyll branch in response to conditions suitable for photosynthetic growth. ChlI and BchD have molecular weights between 38-42kDa [[cite:PUB00000550], [cite:PUB00002318]].</p>
