Artificial P450/reductase fusion enzymes: what can we learn from their structures?

abstract：:The methylotrophic yeast Pichia pastoris is often used as an organism for the heterologous expression of proteins and has been used already for production of a number of glycosyltransferases involved in the biosynthesis of N- and O-linked oligosaccharides. In our recent studies, we have examined the expression in P. p...
