ECF217 ECF proteins

General description: ECF217 has homology to the original group ECF59 (100%) and is present in Planctomycetes (100%) genera Rhodopirellula and Pirellula.

Genomic context conservation: We found membrane-bound protein kinases usually encoded in +1, similarly to original ECF59 (Jogler et al., 2012). Other conserved domains are only present in ECF217s1, with a Planctomycetes extracellular protein (Pfam: Planc_extracel), a dockerin type I repeat (Pfam: Dockerin_1), which takes part in the cellulosome together with a cadherin (source: Pfam(Finn, 2004)) and a tetratricopeptide repeat.

Promoter motif conservation: Predicted target promoter motifs are not conserved.

Summary: Members of ECF217 are encoded close to proteins with a protein kinase domain, similarly to original ECF59 (Jogler et al., 2012). Due to the lack of functional characterization of any of the members of ECF217, it is unclear whether these kinases are regulating the activity of members of ECF217, as speculated for other ECF groups.
