1 GO annotations of cellular component

Name Definition
extracellular region The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.

3 GO annotations of molecular function

Name Definition
aspartyl esterase activity Catalysis of the hydrolysis of an ester bond by a mechanism involving a catalytically active aspartic acid residue.
enzyme inhibitor activity Binds to and stops, prevents or reduces the activity of an enzyme.
pectinesterase activity Catalysis of the reaction: pectin + n H2O = n methanol + pectate.

2 GO annotations of biological process

Name Definition
cell wall modification The series of events leading to chemical and structural alterations of an existing cell wall that can result in loosening, increased extensibility or disassembly.
pectin catabolic process The chemical reactions and pathways resulting in the breakdown of pectin, a polymer containing a backbone of alpha-1,4-linked D-galacturonic acid residues.
