Table 3 List of the structural and functional properties of pectin-deacetylating esterases belonging to CE-8 and CE-12 of carbohydrate esterases

From: Structural and functional properties of pectin and lignin–carbohydrate complexes de-esterases: a review

Strain, PDB ID, CE class Catalytic residues and reaction type CATH and Pfam Enzyme and fold
Substrates and Refs
Erwinia chrysanthemi, [1QJV], CE-8 Asp178, Asp199, Arg267
Aspartic esterase
3-Solenoid
Pectinase lyase C-like pectinesterase
Pectin methyl esterase, single stranded right-handed β-helix, pectin present in cell wall polysaccharides is hydrolyzed to pectate and methanol (Jenkins et al. 2001)
Aspergillus aculeatus, [1DEX], CE-12 Ser9, His195, Asp192
Serine esterases
3-Layer α/β sandwich
Rossmann fold
GDSL-like lipase/acylhydrolase
Rhamnogalacturonan acetylesterase flavodoxin-like (SGNH hydrolase). Rhamnogalacturonan present in the cell walls. RGAE functions in coordination with rhamnogalacturonan lyases and hydrolases (Mølgaard et al. 2000)
