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}.
