..., the L. donovani r Ld MAcP–mRFP1 promastigotes generated in this study, showed significantly higher infectivity and virulence indexes than control parasites in the infection of J774 mouse macrophages highlighting thereby a role for Ld MAcP in the parasite's virulence. ecto-enzyme histidine acid...

... to be strictly intracellular, is identified as a cell-surface phosphoprotein. Key words: ecto-enzyme, extracellular ion receptor, membrane protein, peptide analysis, phosphorylation. cation of the highly phosphorylated protein p100 (ecto-p100) was finally achieved by using a technique of radioactivity detection...
