This is an N-terminal immunoglobulin (Ig)-like domain found in esterases such as EstA. Analysis of the EstA structure confirms that it is a member of the alpha/beta hydrolase family, with a conserved Ser-Asp-His catalytic triad. The Ig-like domain presumably plays a role in the multimerization of EstA into an unusual hexameric structure. Additionally, it may also participate in the catalysis of EstA by guiding the substrate to the active site [1].	Domain
