Minimum number of stalk domains per protein and proportion of identified adhesive domains in FA-like proteins: a Number of FA-like proteins identified depending on the number of required stalk domains. All annotated stalk domains are counted, regardless whether or not they belong to the same or different stalk domain families. b Frequency of adhesive domains in combination with at least one known stalk domain. For proteins with multiple adhesive domains, each domain family is counted once per protein. Throughout this study, we will use blue colouring for stalk domains and red colouring for adhesive domains
