4.2.99.23 | gene TgTCEB1, sequence comparisons and unrooted phylogenetic tree, functional recombinant expression of the mature dimeric enzyme in Escherichia coli. Although the recombinant enzyme is functionally expressed as N-terminal His-tagged protein, removal of the vector-derived sequence including His-tag by protease treatment almost doubles its activity, allowing for accurate assessment of enzyme characteristics.
