Anti-σ factor: As in the case of original ECF38 and ECF39 (Staroń et al., 2009), the proteins in position +1 are putative AS factors, except in ECF38s4, which is associated with YCII-related domain protein in position -1 like proteins from ECF42. These putative AS factors contain one transmembrane helix (67.46%) and no Pfam domain.
Genomic context conservation: Other domains proteins encoded in the genetic context of members of ECF38 are a HIT protein (-1 of ECF38s5 and ECF38s6), a PhoH-like protein (-2 of ECF38s5), a UPF0054 protein (ECF38s5 and ECF38s6), a transporter fused to a DUF21 (ECF38s5 and ECF38s6), a SURF1 protein (+2 of ECF38s1), a DUF3097 (ECF38s5 and ECF38s6), DnaJ (ECF38s5 and ECF38s6), a protein with a DeoR-like helix-turn-helix domain fused to the C-terminal domain of HrcA (ECF38s5 and ECF38s6), a DUF4870 (ECF38s5), a RNA methyltransferase (ECF38s5 and ECF38s6), a 50S ribosome-binding GTPase (ECF38s5), a YbaB/EbfC protein (ECF38s1), an amino acid kinase with an ACT domain (ECF38s1), a DUF5063 (ECF38s1), a semialdehyde dehydrogenase (ECF38s1), RecR (ECF38s1) and a fructose-bisphosphate aldolase class-II (ECF38s4).
Promoter motif conservation: Predicted target promoter motifs are subgroup-specific. In subgroups ECF38s1, ECF38s6 and ECF38s9 there is AACC in -35 and TC in -10. These motifs agree with original ECF39 (Rhodius et al., 2013).
