  ABSTRACT  
 
The recently discovered small ubiquitin-related modifier SUMO-1 belongs to the growing family of ubiquitin-related proteins involved in postranslational protein modification. Unlike ubiquitin, SUMO-1 does not appear to target proteins for degradation but seems to be involved in the modulation of protein-protein interactions. Independent studies demonstrate an essential function of SUMO-1 in the regulation of nucleo-cytoplasmic transport, and suggest a role in cell-cycle regulation and apoptosis. Here, we present the first three-dimensional structure of SUMO-1 solved by NMR. Although having only 18% amino acid sequence identity with ubiquitin, the overall structure closely resembles that of ubiquitin, featuring the betabetaalphabetabetaalphabeta fold of the ubiquitin protein family. In addition, the position of the two C-terminal Gly residues required for isopeptide bond formation is conserved between ubiquitin and SUMO-1. The most prominent feature of SUMO-1 is a long and highly flexible N terminus, which protrudes from the core of the protein and which is absent in ubiquitin. Furthermore, ubiquitin Lys48, required to generate ubiquitin polymers, is substituted in SUMO-1 by Gln69 at the same position, which provides an explanation of why SUMO-1 has not been observed to form polymers. Moreover, the hydrophobic core of SUMO-1 and ubiquitin is maintained by conserved hydrophobic residues, whereas the overall charge topology of SUMO-1 and ubiquitin differs significantly, suggesting specific modifying enzymes and target proteins for both proteins.

Figure 6.
Figure 6. Stereo view of a superposition of the structures of SUMO-1 (black) and ubiquitin (red) using the Program O [Jones et al 1991]. The overlay of the C^α backbone shows the similarity between the two protein cores of SUMO-1 and ubiquitin, although these proteins share only 18% sequence identity. Also marked are side-chains of Gln69 of SUMO-1 and Lys48 of ubiquitin, which is important for the formation of polyubiquitin and which are located at the same position. The indicated C-terminal di-glycine motif is localized in a very flexible region, functionally conserved and located in similar positions relative to the overall protein fold.
Figure 7.
Figure 7. Comparison of the surfaces of SUMO-1 (a and b) and ubiquitin (c and d). Shown are two opposite surface views of SUMO-1 and ubiquitin rotated around the longitudinal axis by 160° and by ±80° as compared to the front view shown in Figure 5 and Figure 6. The corresponding orientations are indicated by the C^α backbone visible underneath the surface. The charge topology was calculated and coloured according to the electrostatic potential over a range of approximately −20 kT/e (in red) to +20 kT/e (in blue) using the program GRASP [Nicholls et al 1991]. The first view of SUMO-1 (a) displays positive charged epitopes (Arg54, Lys46, Lys25, Lys23, Lys17 and Lys16) absent on the corresponding surface of ubiquitin (c) with the exception of SUMO-1 Lys25 (a), and ubiquitin Lys6 (c). The second view of SUMO-1 (b) reveals a large negatively charged surface (Glu89, Asp86, Glu85 and Glu84) together with a negatively charged pocket (Glu83, Glu18, Glu15, Asp12, Glu11 and Glu20), which are not conserved on the corresponding surface of ubiquitin (d).

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
