Structure-function relationships of CldA: a unique functional intermediate between starch hydrolases and cyclomaltodextrin glucanotransferases.
Overall, structural and functional analysis of CldA showed that it diverges from canonical GH13_2 CGTases by lacking C-terminal DE domains, shifting its intramolecular transglycosylation specificity toward hydrolysis through an intriguing starch concentration-dependent product-length mechanism.
