Protein Family Models

This family consists of tail assembly proteins from lambdoid and T1 phages and related prophages, e.g. the tail assembly protein I (TAPI). Members of this family contain a core ubiquitin fold domain [1]. The exact function of TAPI is not clear but it is not incorporated into the mature tail. Gene neighborhoods reveal that TAPI co-occurs with genes encoding the host-specificity protein TapJ, and TapK, which contains a JAB metallopeptidase fused to an NlpC/P60 peptidase. It is proposed that the TAPI protein is processed by the peptidase domains of TapK [1]. [1]. 16859499.
