    Protein Summary

    Gene a2ld1 from Mus musculus encodes the NP_663441 amino acid sequence that belongs to the AIG2-like group (PF06094). It has some similarity to uncharacterized proteins involved in cation transport (COG3703).

    SCOP classifies 2kl2 structure in the alpha+beta class, gamma-glutamyl cyclotransferase (GGCT)-like (super)family. Significant structural similarity to GGCT like PDB:3jub (Z-scr=21), PDB:2qik (Z-scr=12), PDB:1v30 (Z-scr=10), and PDB:2g0q, PDB:2i5t, PDB:1xhs (Z-scr=9) is detected by DALI.

    Analysis of the crystallographic packing of 1vkb (crystal structure of 2kl2) using the PQS server {Henrick, 1998 #73} indicates that a monomer is the biologically relevant form. Conserved residues (Pro51, Tyr88, Phe113, Tyr115) form a long cleft. Two formic acid  molecules (from the crystallization solution) are present in this cleft. Conserved Asp79 is not part of the cleft but interacts with Tyr115. The second (separate) cluster of conserved residues includes Glu65, Tyr68, and His117 [Ref].
