Redesign of the Phosphate Binding Site of L-Rhamnulose- 1-Phosphate Aldolase towards a Dihydroxyacetone Dependent Aldolase
The aldol addition of unphosphorylated dihydroxyacetone (DHA) to aldehydes catalyzed by L‐rhamnulose‐1‐phosphatealdolase (RhuA), a dihydroxyacetonephosphate‐dependent aldolase, is reported. Moreover, a single point mutation in the phosphate binding site of the RhuA wild type, that is, substitution of aspartate for asparagine at position N29, increased by 3‐fold the of aldol addition reactions of
