UniprotKB/SwissProt ID: O82777 (O82777)
Gene Name:
sbt3
Organism: Solanum lycopersicum (Tomato)
Function: Serine protease (PubMed:19332543, PubMed:19407393, PubMed:19805099, PubMed:27259555, PubMed:27451395). Has preference for Gln in the P1 position and Lys in the P2 position of oligopeptide substrates. Active also with His in the P1 position (PubMed:19332543). Involved in resistance against insects partly by regulating expression of systemic wound response genes and possibly by its post-ingestive activity in the insect gut. Apart from the role in defense, may be involved in regulation of pectin methylesterases (PMEs) activity and pectin methylesterification of the cell wall (PubMed:27259555)
