Domain architecture of two new lysozyme families: COG3926/DUF847 and COG5526. The lengths of domains are approximately to scale. Horizontal braces together with the arrows under them suggest homology relationship between domains that can be linked by PSI-BLAST with significant e-values. The two lysozyme-associated transmembrane modules are shown with dotted boundary lines. Predicted transmembrane regions are marked rectangles, with one low confidence prediction shown with dotted boundary line. NCBI gene identification (gi) numbers and species names of representative sequences are shown. The number of proteins with a domain architecture is shown in parentheses after the domain diagram. (a) Single-domain proteins of COG3926/DUF847; (b) the COG3926/DUF847 member with a signal peptide; (c) COG3926/DUF847 members with LATM1; (d) T4 lysozyme family members with LATM1; (e) the COG3926/DUF847 member with LATM2; (f) COG5526 members with PGB and LATM2; (g) single-domain COG5526 members.
