Special features: In agreement with original ECF106 (Staroń et al., 2009), proteins from new ECF106 encoded AS factors with one transmembrane helix (97.14%) in position +1 (except ECF106s6). These AS factors contain a DUF4367 in most of its subgroups.
Promoter motif conservation: Putative target promoter motifs are not conserved, indicating lack of autoregulation of members of ECF106.
Number of representative ECFs: 134
Number of non-redundant ECFs: 247
Sequences with C-terminal extension: 0.00%
Sequences with N-terminal extension: 0.00%
Overrepresented class: Clostridia [60.45%]
