BACKGROUND Leishmaniasis represents a major public health concern in tropical and sub-tropical countries. At present, there is no efficacious vaccine against the disease and new control methods are needed. One way to access this important goal is to knock out genes of specific macromolecules to evaluate the effect of deletion on the growth, multiplication, pathogenesis and immunity of the paras...
PIG-L/GPI12 proteins are endoplasmic reticulum-resident membrane proteins involved in the second step of glycosylphosphatidylinositol anchor biosynthesis in eukaryotes. We show that the Entamoeba histolytica PIG-L protein is optimally active in the acidic pH range. The enzyme has an intrinsic low level of de-N-acetylase activity in the absence of metal and is significantly stimulated by divalen...

Glycosylphosphatidylinositol (GPI) is used as a membrane anchor by many eukaryotic cell-surface proteins. The second step of GPI biosynthesis is de-N-acetylation of N-acetylglucosaminylphosphatidylinositol (GlcNAc-PI). We have previously cloned the rat PIG-L gene by expression cloning that complemented a mutant Chinese hamster ovary cell line defective in this step. Here we show that recombinan...
The TT1542 protein from Thermus thermophilus HB8 is annotated as a conserved hypothetical protein, and belongs to the DUF158 family in the Pfam database. A BLAST search revealed that homologs of TT1542 are present in a wide range of organisms. The TT1542 homologs in eukaryotes, PIG-L in mammals, and GPI12 in yeast and protozoa, have N-acetylglucosaminylphosphatidylinositol (GlcNAc-PI) de-N-acet...
