We tried to clarify the reaction mechanism of the two enzymes involved in the construction and cyclization of tetrapyrrole, based on their crystal structure. In particular, hydroxymethylbilane synthase (HMBS) has a dipyrromethane cofactor and combines four molecules of porphobilinogen as substrates sequentially to form a linear tetrapyrrole, hydroxymethylbilane. We separated enzyme-substrates complexes depending on the number of bound substrates, and succeeded in X-ray crystal structure analysis of HMBS in complex with two substrate molecules. In its crystal structure, compared to the holo form with no substrate, the cofactor moved to the far side of the active site and the two substrate molecules located in the space where originally occupied by the cofactor. These results indicate that the active site of HMBS changes its conformation greatly during the tetrapyrrole construction from substrates.
