However, it was shown in E.coli that the substrate of the enzymatic reaction is not dihydrodipicolinate (DHDP) but in fact (2S,4S)-4-hydroxy-2,3,4,5-tetrahydrodipicolinic acid (HTPA), the product released by the DapA-catalyzed reaction.

HprK/P also catalyzes the pyrophosphate-producing, inorganic phosphate-dependent dephosphorylation (phosphorolysis) of seryl-phosphorylated HPr (P-Ser-HPr). The two antagonistic activities of HprK/P are regulated by several intracellular metabolites, which change their concentration in response to the absence or presence of rapidly metabolisable carbon sources (glucose, fructose, etc.) in the growth medium.

Homotetramer. Forms an RuvA(8)-RuvB(12)-Holliday junction (HJ) complex. HJ DNA is sandwiched between 2 RuvA tetramers; dsDNA enters through RuvA and exits via RuvB. An RuvB hexamer assembles on each DNA strand where it exits the tetramer. Each RuvB hexamer is contacted by two RuvA subunits (via domain III) on 2 adjacent RuvB subunits; this complex drives branch migration.

RuvA specifically binds to HJ cruciform DNA, conferring on it an open structure. The RuvB hexamer acts as an ATP-dependent pump, pulling dsDNA into and through the RuvAB complex. HJ branch migration allows RuvC to scan DNA until it finds its consensus sequence, where it cleaves and resolves the cruciform DNA.

During trans-translation Ala-aminoacylated tmRNA acts like a tRNA, entering the A-site of stalled ribosomes, displacing the stalled mRNA. The ribosome then switches to translate the ORF on the tmRNA; the nascent peptide is terminated with the 'tag peptide' encoded by the tmRNA and targeted for degradation. The ribosome is freed to recommence translation, which seems to be the essential function of trans-translation.
