List of Arabidopsis proteins (Protein-ID) that contain a manually curated RING domain according to the criteria described in the text. The table is divided into three principal sections: RING domains of the RING-HC type; RING domains of the RING-H2 type; and RING-variant domains. In addition, the domains are ordered in numbered clusters according to a single-linkage-clustering method with a 10^-15 threshold as described in the text. If an individual domain meets the requirements of one of the stringent patterns 1 to 4 (S1-S4) (see Table 2), it is indicated by a plus sign, if not, it is indicated by a minus sign. Additional remarks such as previously assigned gene names and significant similarities are given in the last column, The remark 'likely not to be a RING' refers to the presence of an aromatic residue two positions in front of metal-ligand position 7 as outlined in the text.
