| 5.1.3.3 | alpha-D-glucose = beta-D-glucose | the mechanism of the enzymatically catalyzed mutarotation is basically different from that of the nonenzymatically catalyzed mutarotation. The mutarotase acts primarily as a base catalyst. The enzymatically catalyzed mutarotation proceeds via the acyclic aldehyde form of the aldose | Escherichia coli |
