putative alginate O-acetyltranferases AlgJ, AlgV, and similar proteins; The alginate biosynthesis protein AlgX appears to be directly involved in the O-acetylation of alginate, an exopolysaccharide that is associated with the formation of persistent biofilms, such as those by mucoid strains of Pseudomonas aeruginosa that affect patients suffering from cystic fibrosis. Its N-terminal catalytic domain resembles SGNH hydrolases, though with a permuted topology. The active site matches that of the SGNH hydrolases, is well conserved, and has been verified experimentally. Members of this family have been annotated as AlgJ or AlgV, and they closely resemble AlgX in sequence and function, although they lack the C-terminal carbohydrate binding domain of AlgX.

81-345 1.95e-105

SGNH hydrolase-like domain, acetyltransferase AlgX; ALGX is a family found in bacteria. The domain demonstrates catalytic activity similar to that of the SGNH hydrolase-like domain, with the typical Ser-His-Asp triad found in this enzyme. Alginate is an exopolysaccharide that contributes to biofilm formation. ALGX is secreted into the biofilm and is responsible for the acetylation of biofilm polymers that help protect them from host destruction.

64-348 3.48e-53

Uncharacterized proteins similar to putative alginate O-acetyltranferase; The alginate biosynthesis protein AlgX appears to be directly involved in the O-acetylation of alginate, an exopolysaccharide that is associated with the formation of persistent biofilms, such those as by mucoid strains of Pseudomonas aeruginosa that affect patients suffering from cystic fibrosis. Its N-terminal catalytic domain resembles SGNH hydrolases, though with a permuted topology. The active site matches that of the SGNH hydrolases, is well conserved, and has been verified experimentally. Members of this uncharacterized family similar to AlgX_N have been annotated as cell division proteins FtsQ, although they share little or no similarity with experimentally characterized members of the FtsQ family.

This N-terminal catalytic domain resembles SGNH hydrolases, though with a permuted topology. The active site matches that of the SGNH hydrolases, is well conserved, and has been verified experimentally. AlgX contains a C-terminal carbohydrate binding domain that belongs to the wider family of CBM6-CBM35-CBM36_like domains.
