UniprotKB/SwissProt ID: Q9SDM9 (Q9SDM9)
Gene Name:
NSP1
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Specifier protein responsible for constitutive and herbivore-induced simple nitrile formation, especially in seedlings and roots (PubMed:18987211, PubMed:19224919, PubMed:27990154). Promotes simple nitriles, but not epithionitrile or thiocyanate formation (PubMed:18987211, PubMed:19224919). Converts allylglucosinolate (allyl-GSL), 4-methylsulfinylbutylglucosinolate, 4-methylthiobutylglucosinolate, 2-propenylglucosinolate (sinigrin), indol-3-ylmethylglucosinolate (glucobrassicin), benzylisothiocyanate and benzylglucosinolate (glucotropaeolin) to their corresponding simple nitriles in the presence of myrosinase (PubMed:18987211, PubMed:19224919, PubMed:22954730). Catalyzes mainly the conversion of benzylisothiocyanate when benzylglucosinolate is used as the initial substrate of myrosinase (PubMed:19224919, PubMed:22954730). Involved in the regulation of glucosinolate content in seeds, during stratification and germination (PubMed:31850033)
