Molecular Modeling of Myrosinase from Brassica oleracea: A Structural Investigation of Sinigrin Interaction.

ABSTRACT: Myrosinase, which is present in cruciferous plant species, plays an important role in the hydrolysis of glycosides such as glucosinolates and is involved in plant defense. Brassicaceae myrosinases are diverse although they share common ancestry, and structural knowledge about myrosinases from cabbage (Brassica oleracea) was needed. To address this, we constructed a three-dimensional model structure of myrosinase based on Sinapis alba structures using Iterative Threading ASSEmbly Refinement server (I-TASSER) webserver, and refined model coordinates were evaluated with ProQ and Verify3D. The resulting model was predicted with β/α fold, ten conserved N-glycosylation sites, and three disulfide bridges. In addition, this model shared features with the known Sinapis alba myrosinase structure. To
