Homotrimer (PubMed:20455268, PubMed:20816983).

Interacts directly with the central domain of TolA and with PBP1B (PubMed:11994151, PubMed:20816983, PubMed:25951518). Binding to TolA disrupts the homotrimer to form a YbgF/TolA heterodimer with weak affinity (PubMed:20816983).

Forms a quaternary complex with PBP1B-LpoB and TolA (PubMed:25951518).

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1.
