From: Phylogenetic distribution and membrane topology of the LytR-CpsA-Psr protein family
Architectures of the LytR-CpsA-Psr proteins used for secondary structure prediction. Most of the sequences showed a for LytR-CpsA-Psr proteins typical domain organization with a short N-terminal tail, a single transmembrane domain (red), and a long C-terminal part carrying the LytR-CpsA-Psr domain (light blue). An exception of this architecture is found in the group of CpsA-like proteins, represented by CpsX of S. agalactiae (Q3K0S7_STRA1), which contain three predicted transmembrane helices and a DNA polymerase processivity factor domain (orange) in addition to the LytR-CpsA-Psr domain. The sequence identifiers correspond to the UniProt entry names (see Additional file 4).
