Abstract

The front cover picture was designed by Emina Mehić and Lucija Hok, and illustrated by Josipa Zeba. (© Josipa Zeba. Reproduced with permission.) It depicts the halohydrin dehalogenase-catalysed conversion of epoxides. Extensive screening of enzymes from group B revealed several highly enantioselective transformations, with HheB showing higher enantioselectivity and activity toward a larger panel of substrates compared to HheB2. By using site-directed mutagenesis, residues 120 and 125 were found to be responsible for higher enantioselectivity of HheB compared to HheB2. Due to remarkable activity and enantioselectivity, B-group HHDHs emerged as a catalyst of choice for the synthesis of bulky tertiary alcohols.
