The activity of single-chain cathepsin L was found to be markedly dependent on cysteine concentration, while a covalent, proteolytically active cathepsin L/cystatin complex was less cysteine-dependent. Cysteine levels and ionic strength did not affect the stability of either enzyme form and both enzyme forms were found to be stable for significant periods(More)
Cell surface heparan sulphate (HS) mediates infection for many viruses from diverse families. We demonstrated significant antiviral potencies for a number of HS mimetics against a cloned strain of Enterovirus 71 (EV71) in a previous study. Thus, the involvement of HS in mediating viral infection of isolates of human enteroviruses was investigated in Vero(More)
Dengue virus (DENV) is a major public health threat worldwide. A key element in protection from dengue fever is the neutralising antibody response. Anti-dengue IgG purified from DENV-2 infected human sera showed reactivity against several peptides when evaluated by ELISA and epitope extraction techniques. A multi-step computational approach predicted six(More)
