Homology within the N-terminal extension of cysteine proteinases.
It is now well established that the cysteine proteinases of plants (e.g. papain, actinidin, bromelain) and animals (e.g. cathepsins B, H and L) are homologous (see Takio et al., 1983) and almost certainly evolved from a common ancestral protein. For all but one of the cysteine proteinases sequenced to date the N-terminal residues can be exactly aligned with one another at a distance of 25-29 re...
متن کاملAmino acid substitutions in the N-terminal segment of cystatin C create selective protein inhibitors of lysosomal cysteine proteinases.
We used site-directed mutagenesis to alter the specificity of human cystatin C, an inhibitor with a broad reactivity against cysteine proteinases. Nine cystatin C variants containing amino acid substitutions in the N-terminal (L9W, V10W, V10F and V10R) and/or the C-terminal (W106G) enzyme-binding regions were designed and produced in Escherichia coli. It was discovered that the inhibition profi...
متن کاملCysteine proteinases and the pathogenesis of amebiasis.
Amebiasis is a major cause of morbidity and mortality throughout the tropical world. Entamoeba histolytica is now recognized as a separate species from the morphologically identical E. dispar, which cannot invade. Cysteine proteinases are a key virulence factor of E. histolytica and play a role in intestinal invasion by degrading the extracellular matrix and circumventing the host immune respon...
متن کاملContrasting membrane interaction mechanisms of AP180 N-terminal homology (ANTH) and epsin N-terminal homology (ENTH) domains.
Epsin and AP180/CALM are endocytotic accessory proteins that have been implicated in the formation of clathrin-coated pits. Both proteins have phosphatidylinositol 4,5-bisphosphate (PtdIns(4,5)P2)-binding domains in their N termini, but these domains are structurally and functionally different. To understand the basis of their distinct properties, we measured the PtdIns(4,5)P2-dependent membran...
متن کاملLabelling of cysteine proteinases in purified lysosomes.
NADH could not be freeze-stored at -25°C in 50 mMsodium phosphate buffer (pH range 6-8 20°C) without serious loss of the nucleotide; however, no losses were seen upon freeze storage in 50 mM-Hepes buffer (pH range 7-8, 20°C). The rate of NADH degradation was greater (approx. 2-fold) in 50 mMthan in 5 mM-sodium phosphate buffer, although NADH values at both buffer concentrations were similar (5%...
