The isolated, extracellular fibrils of the myxobacterium, Myxococcus xanthus , are capable of carrying out ADP‐ribosylation. The substrate for the ADP‐ribosylation is reactive with monoclonal antibody 2105, which has been shown to be directed specifically against the integral fibril proteins. The extracellular fibrils thus contain both the ADP‐ribosyl transferase and the substrate for the ribosylation. This process may play a role in the contact‐mediated cell–cell interactions that are an important part of the social behaviour of M. xanthus .
