YchN forms a homohexameric dimer of trimers (Shin, 2002). YchN is a predicted sulfur relay for intracellular sulfur reduction since paralogs TusB and TusD form a heterohexameric dimer of heterotrimers with TusB that is a sulfur relay system for tRNA modification that is structurally similar to YchN (Numata, 2006). TusB, TusD and YchN are paralogs of the Pfam PF02635 family.
