Structure of 2ijz-A chain
Structural Analysis of 2ijz-A chain
From here, the results of the conserved regions in the sequence is taken from the evolutionary analysis part. These conserved regions are then marked out in red in the following image below (Fig:3.5).
Structural Comparison of 2ijz-A and Respective Proteins
Amino acids involved in the catalytic mechanism of M18metallopeptidases are unknown, although histidines are likely involved in Zn2+ coordination (Wilk .et, al. 2002). Above shown is the histidine site at poisition 82 in the sequence and it is conserved in structural alignment with the other three proteins that are marked out in the DALI search. From literature review papers, the following results have been deduced and dicuss in the discussion.
