Anti-σ factor: Members of this group contain an AS factor encoded in position +1 with a DUF4179 in most of the cases. Proteins encoded in this position contain one transmembrane helix (88.7%). The genetic context conservation does not extend beyond the AS factor.
Summary: Members of ECF23 are regulated by single transmembrane AS factors encoded in +1 that contain a DUF4179. The genetic context conservation does not extend beyond the AS factor.
Number of representative ECFs: 601
Number of non-redundant ECFs: 1149
Sequences with C-terminal extension: 0.26%
Sequences with N-terminal extension: 0.17%
Overrepresented class: Clostridia [51.25%]
