DE   RING-type E3 ubiquitin transferase (cysteine targeting).
AN   RING E3 ligase.
CA   [E2 ubiquitin-conjugating enzyme]-S-ubiquitinyl-L-cysteine + [acceptor
CA   protein]-L-cysteine = [E2 ubiquitin-conjugating enzyme]-L-cysteine +
CA   [acceptor protein]-S-ubiquitinyl-L-cysteine.
CC   -!- This relatively rare subpopulation of RING-type E3 ubiquitin
CC       transferases (cf. EC, found in mammals and herpes viruses,
CC       can transfer ubiquitin to a cysteine residue in target proteins.
CC   -!- Additional ubiquitin molecules are polymerized on top of the initial
CC       ubiquitin molecule by formation of an isopeptide linkage with
CC       lysine(48) in the pre-attached ubiquitin (2).
