Comparison of the domain architectures of T. kodakaraensis KOD1 ChiA and “M. degradans” strain 2-40 ChiB. Gray boxes, type II secretion signal; black boxes, predicted lipobox; SSS, polyserine domains; hatched box, acidic repeat domain; crosshatched boxes, chitin binding domains. Black bars indicate the truncated portions of ChiB created for this work. GH18N is located between amino acids 221 and 605 of ChiB. GH18C is located between amino acids 860 and 1254.
