ECF271 ECF proteins

General description: Members of ECF271 are homologous to proteins from original ECF03 (2.5%) and are present in Chloroflexi (81.82%) (ECF271s1) and Acidobacteria (9.09%) from the genus Bryobacter (ECF271s2).

Anti-σ factor: Members of this group encode a soluble (100%) zinc-finger putative AS factor in +1.

Promoter motif conservation: Promoter motifs are only conserved in ECF271s1 and contain GCTGCTG in -35 and GXTCA in -10.

Summary: Unlike original ECF03 (Staroń et al., 2009), members of ECF271 are regulated by a soluble ZAS encoded in +1.

Gene neighbourhood conservation analysis


Overall Pfam domain distribution: Cumulative frequency of Pfam domains across the genetic neighborhoods. Frequency is expressed as number of Pfam domains per ECF sigma factor. Only domains present in more than 75% of the neighborhoods are shown. Genetic neighborhoods contain the proteins encoded in ±10 from the ECF coding sequence. Only the non-overlapping, highest scoring domains are considered positive. If a protein contains several copies of a domain, only one instance is further considered. In order to avoid sequence bias, only proteins from assemblies defined as "representative" or "reference" by NCBI are included (see https://www.ncbi.nlm.nih.gov/assembly/help/).
Pfam domain distribution per position: Frequency of Pfam domain architectures in the proteins encoded in ±10 (x-axis) from the ECF coding sequences. Frequency is expressed as number of times a certain domain architecture appears per ECF sigma factor. Only the highest scoring domains with no position overlap are considered in the domain architectures. Note that the order of the Pfam domains in domain architectures may differ from their name. When a protein contains several copies of a domain, only one instance is further considered. Only domain architectures present in more than 20% of the proteins encoded in any position are shown. In order to avoid sequence bias, only proteins from assemblies defined as "representative" or "reference" by NCBI are included (see https://www.ncbi.nlm.nih.gov/assembly/help/).
