Fig. 1From: An accurate strategy for pointing the key biocatalytic sites of bre2691A protein for modification of the brevilaterin from Brevibacillus laterosporusAmino acid sequence comparison of bre2691A with PheA. Specificity-conferring code residues were marked with an asterisk. The secondary structural elements of bre2691A and PheA were indicated by bars above or below the sequence. The conserved positions were shown in redBack to article page
