A novel oligomeric hydrolase (LI22) from Listeria innocua CLIP 11262 was identified, characterized, and immobilized for industrial application. Sequence analysis of LI22 revealed a putative catalytic triad (Ser(10)-Asp(176)-His(179)), and a conserved sequence motif Ser(S)(10)-Gly(G)(77)-Asn(N)(79)-His(H)(179) with moderate identities (<30%) with other...
