While there is evidence of nitric oxide (NO)-dependent signalling via the second messenger cyclic guanosine 3',5'-monophosphate (cGMP) in plants, guanylate cyclases (GCs), enzymes that catalyse the formation of cGMP from guanosine 5'-triphosphate (GTP) have until recently remained elusive and none of the candidates identified to-date are NO-dependent.

Retinoblastoma-binding protein-6 (RBBP6) plays a facilitating role, through its RING finger-like domain, in the ubiquitination of p53 by Hdm2 that is suggestive of E4-like activity. Although the presence of eight conserved cysteine residues makes it highly probable that the RING finger-like domain coordinates two zinc ions, analysis of the primary sequence(More)
