'''Crystal Structure of Ubiquitin Carboxy-terminal Hydrolase L1 (UCH-L1)'''<br />
'''Crystal Structure of Ubiquitin Carboxy-terminal Hydrolase L1 (UCH-L1)'''<br />


==Overview==
==Overview==
The ubiquitin C-terminal hydrolase UCH-L1 (PGP9.5) comprises &gt;1% of total, brain protein but is almost absent from other tissues [Wilkinson, K. D., et al. (1989) Science 246, 670-673]. Mutations in the UCH-L1 gene have, been reported to be linked to susceptibility to and protection from, Parkinson's disease [Leroy, E., et al. (1998) Nature 395, 451-452;, Maraganore, D. M., et al. (1999) Neurology 53, 1858-1860]. Abnormal, overexpression of UCH-L1 has been shown to correlate with several forms of, cancer [Hibi, K., et al. (1998) Cancer Res. 58, 5690-5694]. Because the, amino acid sequence of UCH-L1 is similar to that of other ubiquitin, C-terminal hydrolases, including the ubiquitously expressed UCH-L3, which, appear to be unconnected to neurodegenerative disease, the structure of, UCH-L1 and the effects of disease associated mutations on the structure, and function are of considerable importance. We have determined the, three-dimensional structure of human UCH-L1 at 2.4-A resolution by x-ray, crystallography. The overall fold resembles that of other ubiquitin, hydrolases, including UCH-L3, but there are a number of significant, differences. In particular, the geometry of the catalytic residues in the, active site of UCH-L1 is distorted in such a way that the hydrolytic, activity would appear to be impossible without substrate induced, conformational rearrangements.
