| Note | Family created after the characterization of Phytophthora infestans enzymes by Sabbadin et. al., (PMID:34385392). AA17 are copper-dependent lytic polysaccharide monooxygenases (LPMOs) found in oomycetes; binding and cleavage of homogalacturonan with oxidation of C-4 has been demonstrated for three AA17 LPMOs from Phytophtora infestans; oxidative polygalacturonase; C4-oxidative cleavage of polygalacturonic acid, generating a C4-ketone in a b-position relative to one carboxylic group, resulting in an unstable b-keto acid that undergoes spontaneous decarboxylation and tautomerization |
