Protein Variants

EC Number Protein Variants Comment Organism
2.3.1.157 T80S/Y97N the mutant enzyme shows 6.5times-higher activity, compared to that of the wild-type ST0452 protein, revealing that these two substituted residues function cooperatively to increase N-acetylglucosamine-1-phosphate uridyltransferase activity Sulfurisphaera tokodaii
2.3.1.157 Y97N the mutant enzyme exhibits over 4 times higher N-acetylglucosamine-1-phosphate uridyltransferase activity, compared with that of the wild-type ST0452 protein. The three-dimensional structure of the Y97N protein is not changed by this substitution but the interactions with the substrate are slightly modified, which might cause the activity to increase. The crystal structure of the Y97N protein shows that positions 146 (Glu) and 80 (Thr) form interactions with GlcNAc, and an engineering strategy is applied to these residues to increase activity Sulfurisphaera tokodaii
2.3.1.276 T80S/Y97N the mutant enzyme shows 6.5times-higher activity, compared to that of the wild-type ST0452 protein, revealing that these two substituted residues function cooperatively to increase N-acetylglucosamine-1-phosphate uridyltransferase activity Sulfurisphaera tokodaii
2.3.1.276 Y97N the mutant enzyme exhibits over 4 times higher N-acetylglucosamine-1-phosphate uridyltransferase activity, compared with that of the wild-type ST0452 protein. The three-dimensional structure of the Y97N protein was not changed by this substitution but the interactions with the substrate were slightly modified, which might cause the activity to increase. The crystal structure of the Y97N protein shows that positions 146 (Glu) and 80 (Thr) form interactions with GlcNAc, and an engineering strategy is applied to these residues to increase activity Sulfurisphaera tokodaii
2.7.7.23 T80S/Y97N the mutant enzyme shows 6.5times-higher activity, compared to that of the wild-type ST0452 protein, revealing that these two substituted residues function cooperatively to increase N-acetylglucosamine-1-phosphate uridyltransferase activity Sulfurisphaera tokodaii
