RT   multicopy gene family during potato tuber development.";
RL   Genetics 172:1263-1275(2006).
CC   -!- FUNCTION: Probable lipolytic acyl hydrolase (LAH), an activity which is
CC       thought to be involved in the response of tubers to pathogens.
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Vacuole {ECO:0000250}.
CC   -!- TISSUE SPECIFICITY: Tuber. {ECO:0000269|PubMed:16322504}.
CC   -!- DEVELOPMENTAL STAGE: Accumulates progressively during tuber formation
CC       from stolon. {ECO:0000269|PubMed:16322504}.
CC   -!- DOMAIN: The nitrogen atoms of the two glycine residues in the GGXR
CC       motif define the oxyanion hole, and stabilize the oxyanion that forms
CC       during the nucleophilic attack by the catalytic serine during substrate
CC       cleavage.
CC   -!- MISCELLANEOUS: Patatin have a dual role as a somatic storage protein
CC       and as an enzyme involved in host resistance.
CC   -!- SIMILARITY: Belongs to the patatin family. {ECO:0000305}.
