    Protein Summary

    The HS_0176 gene of H. somnus 129PT encodes the YP_718383 protein with sequence and structure similar to predicted phosphoglycolate phosphatases (COG0546) (SCOP). Genome context analysis shows a strong functional link (score 0.9) with the ribulose-phosphate 3-epimerase (HS_0175).

    Residues conserved between YP_718383 and COG0546 (Thr118, Lys151, Gly175, Asp176, and Asp180) are clustered together around central part of a deep cleft. This cleft has two openings and is partly occupied by UNL. The other residues that were found (using SAM-T06 server) to be conserved between YP_718383 and similar sequences are also located around the same cleft (Asp10, Asp12, Gly13, Thr118, Asn119, Lys151, Asp176, and Asp180) or clustered together (Phe9, Leu15, Leu104, and Ile219) next to the cleft surrounding residues.

    The 2hsz structure has significant structural similarity to proteins with beta-phosphoglucomutase-like structures, such as for example: phosphonoacetaldehyde hydrolase (PDB:1fez-A; DALI Z-score 22.2; RMSD 2.4; 11% sequence identity within 215 superimposed residues), and beta-phosphoglucomutase (PDB:1o03-A; DALI Z-score 19.8; RMSD 2.9 ; 16% sequence identity within 199 superimposed residues).

    Analysis of the crystallographic packing of 2hsz using the PQS server {Henrick, 1998 #73} indicates that a tetramer is the biologically relevant form.

    Ligand Summary

    The UNL occupies one side of a deep cleft. This cleft has two entrances and several conserved residues in the middle.
