Production of a low molecular weight heparin using recombinant unsaturated glycuronidase, G. Sua, L. Lia, W. Zhong, F. Zhang, R.J. Linhardt, Carbohydrate Polymers, 134, 151–157, 2015.
Abstract
The Δ4,5 unsaturated uronate (4-deoxy-α-l-threo-hex-4-eno-pyranosyluronic acid) residue is produced through the depolymerization of heparin, heparosan, and heparan sulfate with heparin lyases. The recovery of unsaturated uronate containing products is necessary to prepare low molecular weight heparin (LMWH) from heparin or heparosan. In this study, the gene of Δ4,5 and Δ4,5(Δ20) unsaturated glycuronidase (EC# 3.2.1.56) from Pedobacter heparinus (formerly Flavobacterium heparinum) was cloned into pMAL-c2x plasmid. Its fusion protein with MBP was expressed in Escherichia coli TB1. After purification, Δ4,5 unsaturated glycuronidase was evaluated. The Δ4,5(Δ20) glycuronidase showed excellent activity on the unsaturated bonds of the different depolymerized products from Hep I, Hep II, and Hep III on heparin, heparosan, and heparan sulfate.;
