dc.description.abstract | N-acetylglucosamine (GlcNAc), an alternative sugar, is emerging as an important molecule having a multifarious role in Candida albicans including a major role in signaling. GlcNAc Inducible Gene 2, GIG2 is one of the highly upregulated genes in GlcNAc grown cells in C. albicans. Our earlier studies show the involvement of Gig2 in the formation of N-acetylneuraminic (NANA) acid from GlcNAc-6-phosphate through an understudied route. The crystal structure of Gig2 would help us in determining the exact reaction that this enzyme catalyzes. Here the cloning, expression, purification and crystallization of this protein are reported along with preliminary X-ray crystallographic analysis at 2.4Å resolution. The crystal belonged to P2 1 space group, with unit cell parameters a=59.59, b= 54.43, c= 73.29Å; α = 90°, β = 102.7° and γ = 90°. The structure was solved using PDB ID 2CSG as a template which has only 27% identity. Molecular replacement yielded a solution with LLG score of 87. The structure is currently under further refinement. | en_US |
