Octopine synthase

This enzyme [EC 1.5.1.11], also known as D-octopine synthase, catalyzes the reversible reaction of A -(d-1-carboxyethyl)-L-arginine with NAD+ and water to produce L-arginine, pyruvate, and NADH. The enzyme, in the reverse direction, will also act on L-ornithine, L-ly-sine, and L-histidine.

We have used gel retardation assays to study proteins binding to the ARE. We used a probe consisting of the 42 base ARE. When the probe was multimerised in four or six tandem copies, protein, AREF (ARE Factor) from nuclear extracts of anaerobically induced suspension cultures was bound to the probe and showed a ladder of retarded bands (Fig. 2). This ladder of bands was completed specifically by the 4x ARE probe but not by a probe containing four copies of the octopine synthase enhancer element or pUC DNA even in 100-fold excess. Probes which contained one or two copies of the ARE did not show any binding. The need to multimerise the probe presumably results either from low affinity of the protein for the DNA or low abundance of AREF in nuclear extracts. 

Hex motif are found in the octopine synthase (ocs) and nopaline synthase (nos) promoters of the Ti-plasmids (Bouchez et al., 1989), as well as in the cauliflower mosaic virus 35S promoter (as-1 motif) (Katagiri et al.,...
