Fig. 7From: Metabolic engineering of Bacillus subtilis for chiral pure meso-2,3-butanediol productionThe phylogenetic tree based on typical amino acid sequences of AR from 14 2,3-BD producers. The sequences were extracted from the NCBI protein database by a BLAST search. The phylogenetic tree was constructed by the neighbor-joining method with the Poisson correction model by the software MEGA 5Back to article page
