Rhamnogalacturan_acetylesterase_like subgroup of SGNH-hydrolases. Rhamnogalacturan acetylesterase removes acetyl esters from rhamnogalacturonan substrates, and renders them susceptible to degradation by rhamnogalacturonases. Rhamnogalacturonans are highly branched regions in pectic polysaccharides, consisting of repeating -(1,2)-L-Rha-(1,4)-D-GalUA disaccharide units, with many rhamnose residues substituted by neutral oligosaccharides such as arabinans, galactans and arabinogalactans. Extracellular enzymes participating in the degradation of plant cell wall polymers, such as Rhamnogalacturonan acetylesterase, would typically be found in saprophytic and plant pathogenic fungi and bacteria.

GDSL-like Lipase/Acylhydrolase family. This family of presumed lipases and related enzymes are similar to pfam00657.

Lysophospholipase L1 or related esterase [Amino acid transport and metabolism].

SGNH_hydrolase, or GDSL_hydrolase, is a diverse family of lipases and esterases. The tertiary fold of the enzyme is substantially different from that of the alpha/beta hydrolase family and unique among all known hydrolases; its active site closely resembles the typical Ser-His-Asp(Glu) triad from other serine hydrolases, but may lack the carboxlic acid.

The tertiary fold of the enzyme is substantially different from that of the alpha/beta hydrolase family and unique among all known hydrolases; its active site closely resembles the Ser-His-Asp(Glu) triad found in other serine hydrolases.
