Comparisons of the three mature ctenidins and of ctenidin 1 to acanthoscurrin 1. a Alignment of the three mature ctenidins. The fragment of ctenidin 3 that was sequenced by Edman-degradation to determine the position of the additional glycines is underlined. The fragments used to prove the C-terminal processing are underlined by a dotted line. b Comparison of ctenidin 1 to acanthoscurrin 1. All glycine-repeats are highlighted in gray
