Highly efficient aldol additions of DHA and DHAP to N-Cbz-amino aldehydes catalyzed by l-rhamnulose-1-phosphate and l-fuculose-1-phosphate aldolases in aqueous borate buffer
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
