The UBR-box is a 70–80 residue domain and is known to be present in at least seven mammalian proteins (UBR1-7) [1–3], two yeast proteins (Saccharomyces cerevisiae UBR1 and UBR2) [1, 2] and one plant protein (Arabidopsis thaliana PRT6) [2]. The X-ray structures of UBR-box ...
According to domain organization and the ability to carry thioester-linked Ub, E3 ligases can be divided into 4 types: HECT, RING, U-box, and RBR4. RING-type E3 ligases are characterized by the presence of a RING domain, which was first identified in a protein encoded by the Really ...
We previously reported that the Plasmodium falciparum putative serine/threonine protein phosphatase 7 (PP7) is a high-confidence substrate of the cAMP-dependent protein kinase (PKA). Here we explore the function of PP7 in asexual P. falciparum blood stage parasites. We show that conditional disrup...
The U-box (UFD2 homology domain) is a degenerate version of the RING motif that lacks the signature metal-chelating residues (5,6). Unlike the authentic RING finger that is stabilized by binding zinc ions, it has been inferred from the PROMODII model that the U-box is maintained by a ...

Crystal structures of the plant [42], bacterial [43], [44], and human [45] enzymes have been determined and show that the protein is a homodimer with one noncovalently bound FAD per subunit. PPOX is synthesized in the cytoplasm in its mature size and is translocated to the outer surface...
The E3 enzymes are grouped into three families based on the presence of the E3 catalytic core domain: the homology to E6AP carboxyl terminus (HECT), the really interesting novel gene (RING) finger (RNF) and the U-box protein families [12]. The HECT domain is comprised of approximately ...
