algI

Gene
algI
Protein
Probable alginate O-acetylase AlgI
Organism
Pseudomonas aeruginosa (strain ATCC 15692 / DSM 22644 / CIP 104116 / JCM 14847 / LMG 12228 / 1C / PRS 101 / PAO1)
Length
520 amino acids
Function
Together with AlgJ and AlgF, forms an inner membrane complex which probably interacts with the alginate polymerization-transport complex and adds acetyl groups at the O-2 and O-3 positions of mannuronate residues. Acetylation of alginate is important for the architecture of biofilms and increases resistance to opsonic killing in the host.
Similarity
Belongs to the membrane-bound acyltransferase family.

Organism
Pseudomonas syringae pv. tomato (strain ATCC BAA-871 / DC3000)
Length
518 amino acids
Function
Together with AlgJ and AlgF, forms an inner membrane complex which probably interacts with the alginate polymerization-transport complex and adds acetyl groups at the O-2 and O-3 positions of mannuronate residues. Acetylation of alginate is important for the architecture of biofilms and increases the ability of alginate to act as a defense barrier (By similarity).
