The product of gene fromArabidopsis thalianais a 32 kDa, 299-residue protein classified as resembling a myrosinase-binding protein (MyroBP). MyroBPs are found in plants as part of a complex with the glucosinolate-degrading enzyme myrosinase, and are suspected to play a role in myrosinase-dependent defense against pathogens. | ỊFEBS Journal Structure of the putative 32 kDa myrosinase-binding protein from Arabidopsis determined by Sail-nmr 1 -2 2 i-2ai- 2 Mitsuhiro Takeda Nozomi Sugimori Takuya Torizawa Tsutomu Terauchi Akira M.
