abstract：:The glycosylphosphatidylinositol phospholipase C (GPI-PLC) from Trypanosoma brucei is particularly effective in hydrolysing the GPI-anchors of some proteins. The enzyme is inhibited by Zn2+ and p-chloromercurylphenylsulphonic acid, both of which can act as sulphydryl reagents, suggesting that a cysteine residue may be...
