Crystal structure of Peptidyl Arginine Deiminase Type III (PADI3)
Structural highlights
DiseasePADI3_HUMAN Uncombable hair syndrome. The disease is caused by mutations affecting the gene represented in this entry. FunctionPADI3_HUMAN Catalyzes the deimination of arginine residues of proteins.[1] Publication Abstract from PubMedThe Ca(2+)-dependent enzyme peptidyl-arginine deiminase type III (PAD3) catalyses the deimination of arginine residues to form citrulline residues in proteins such as keratin, filaggrin and trichohyalin. This is an important post-translation modification that is required for normal hair and skin formation in follicles and keratocytes. The structure of apo human PAD3 was determined by X-ray crystallography to a resolution of 2.8 A. The structure of PAD3 revealed a similar overall architecture to other PAD isoforms: the N-terminal and middle domains of PAD3 show sequence and structural variety, whereas the sequence and structure of the C-terminal catalytic domain is highly conserved. Structural analysis indicates that PAD3 is a dimer in solution, as is also the case for the PAD2 and PAD4 isoforms but not the PAD1 isoform.
