Structure of GH36 alpha-galactosidase from Thermotoga maritima in complex with intact cyclopropyl-carbasugar.

Structural Snapshots for Mechanism-Based Inactivation of a Glycoside Hydrolase by Cyclopropyl Carbasugars.

Differences at the N-terminus arise from the vector used for expression (primarily a His tag). Differences at the C-terminus arise from the lack of electron density meaning this part could not be modelled.
