additional information Cricetulus griseus protein C-mannosylation is the attachment of alpha-mannopyranose to tryptophan via a C-C linkage. This post-translational modification typically occurs within the sequence motif WXXW, which is frequently present in thrombospondin type-1 repeats (TSRs). TSRs are especially numerous in and a defining feature of the ADAMTS superfamily. Predicted C-mannosylation sites in the ADAMTS superfamily, overview ?
