Fig. 1From: Identification, expression, and purification of DNA cytosine 5-methyltransferases with short recognition sequencesStrategy to identify the MTase genes recognizing short sequence motifs A Scheme used to search the candidate MTases in the databases. B Multiple alignments of the 25 genes. Homologous regions are expressed with thick bars. The same alignment with the single amino acid resolution is provided in Additional file 1: Fig. S2Back to article page
