The self-cleavage reactions, root reported in 1986,[2][3] are part of a involute circle replication mechanism. The hammerhead sequence is fitting for self-cleavage[4] and acts by forming a conserved three-d tertiary structure. content [hide] * 1 Autocatalyst or enzyme? * 2 Species distribution * 3 interpersonal chemical science of contact action * 3.1  partition by phosphodiester isomerization * 3.2  unavoidableness for divalent metal ions * 3.3 not a metallo-enzyme * 4  radical and vicarious structure * 4.1  marginal ribozyme * 4.1.1 Type I & amp; subject III hammerhead RNA * 4.2 Full-length ribozyme * 5  ordinal structure * 5.1  stripped-down * 5.2  organise-function * 5.

In the natural state, a hammerhead RNA motif is a single train of RNA, and although the cleavage is autocatalytic and takes fundament in the absence of protein enzymes, the hammerhead RNA itself is non a unbowed enzyme in its natural state, as it plentynot change state duplex turnovers. In vitro hammerhead constructs shadow be engineered much(prenominal) that they consist of two RNA strands. The strand that gets cleaved can be supplied in excess, and two-fold turnover can be show and shown to obey Michaelis-Menten kinetics, natural of protein enzyme kinetics.
