[carbohydrate recognition domain, C-lectin domains, S-lectin domains]
abbr. CRD. This protein domain of approximately 130 amino acids includes a number of invariant cysteine residues. The C-lectin domain is a carbohydrate binding domain that contains a number of invariant cysteine residues, which form disulfide bonds, and that requires calcium ions for binding. The S-lectin domain is a carbohydrate binding domain that contains cysteine residues as free thiols, contains a number of invariant amino acid positions, and does not require divalent cations for binding. The distinction goes back to work by Drickamer et al (1988) who classified animal lectins into C and S classes.
Note that the terms Ctype carbohydrate recognition domain or
