3D Print and Structural Features of Alpha-amylase
Alpha-amylase is a small enzyme found in saliva (produced by the salivary glands - encoded by genes AMY1A, AMY1B, and AMY1C) and small intestine (produced in the pancreas - encoded by the gene AMY2A). The enzyme starts the digestion of starches by cleaving the long carbohydrate chains into maltose and dextrin).
This printed model can be used to demonstrate how the substrate interacts with the enzyme’s active site (Image 1).
The carbohydrate chain was modeled by threading 5mm melty beads onto a pipe cleaner and then inserted into the groove that represents the active site (Image 2).
Each bead represents one glucose. 2 colors were used to indicate the possible products of multiple reactions of the enzyme with the chain (past cleavage and exiting the active site): red for maltose, white for dextrin (Image 3).
