Various forms of rabbit plasma alpha-1-antiproteinase.

Biochem. Mol. Biol. Int. 46(1) , 27-34, (1998)

Amino acid sequencing of the ficin-derived C-terminal fragments of alpha-1-antiproteinase (also called alpha-1-antitrypsin or alpha-1-proteinase inhibitor) prepared from rabbit plasma revealed the presence of the E isoform, which had been confirmed in the cDN...

Characterization of acid-induced molten globule like state of ficin.

Int. J. Biol. Macromol. 45(3) , 248-54, (2009)

Effect of pH on the conformational behaviour of ficin (EC 3.4.22.3), a cysteine protease from the latex of Ficus carica was monitored by circular dichroism, fluorescence spectroscopy, ANS binding and hydrodynamic studies. The results obtained from near- and f...

Variation in aspects of cysteine proteinase catalytic mechanism deduced by spectroscopic observation of dithioester intermediates, kinetic analysis and molecular dynamics simulations.

Biochem. J. 357(Pt 2) , 343-52, (2001)

The possibility of a slow post-acylation conformational change during catalysis by cysteine proteinases was investigated by using a new chromogenic substrate, N-acetyl-Phe-Gly methyl thionoester, four natural variants (papain, caricain, actinidin and ficin), ...

Production and characterization of two variants of human cystatin SA encoded by two alleles at the CST2 locus of the type 2 cystatin gene family.

Arch. Biochem. Biophys. 352(2) , 199-206, (1998)

Two variants of cystatin SA encoded by two alleles at the CST2 locus of the type 2 human cystatin gene family were expressed in Escherichia coli. One, termed cystatin SA1, is identical to cystatin SA [S. Isemura, E. Saitoh, and K. Sanada J. Biochem. 102, 693-...

Persistence of cefotetan on red blood cells.

Transfusion 44(6) , 849-52, (2004)

Cefotetan can cause severe immune hemolytic anemia that may persist long after the drug is discontinued. To study the binding of cefotetan to RBCs, patients who received cefotetan were followed and tested for the presence of antibody to cefotetan.Patients rec...

A major target for warm immunoglobulin G autoantibodies: the third external loop of Band 3.

Transfusion 53(9) , 1948-55, (2013)

Rh proteins and the Wr(b) antigen, which results from an interaction between Band 3 and glycophorin A, are the most common targets for warm immunoglobulin (Ig)G autoantibodies. Apart from autoanti-Di(b) , a scarce specificity, IgG warm autoantibodies specific...

Application of several types of substrates to ficin-catalyzed peptide synthesis.

Amino Acids 34(1) , 149-53, (2008)

The capability of ficin, a cystine protease, to form peptide bonds was investigated using several types of N-Boc-amino acid phenyl and naphthyl esters as acyl donor components. Enzyme-catalyzed peptide synthesis was carried out under optimized reaction condit...

Use of enzyme treatment to enhance reactivity of HLA and platelet-specific antibodies in solid-phase RBC adherence assays.

Transfusion 42(4) , 476-80, (2002)

Solid-phase RBC adherence (SPRCA) assays (Immucor) detect HLA and/or platelet-specific antibodies. Pretreatment of reagent platelets with enzymes was investigated to determine whether the sensitivity of the assay could be increased.SPRCA testing, following th...

Purification and characterization of extracellular cysteine protease inhibitor, ECPI-2, from Chlorella sp.

J. Biosci. Bioeng. 101(2) , 166-71, (2006)

An extracellular cysteine protease inhibitor (ECPI-2) was purified to homogeneity from the culture filtrate of Chlorella sp. 4533 by the combination of various column chromatographies. The molecular mass of the inhibitor was estimated to be 340 kDa by SDS-PAG...

Effects of reducing, oxidizing and alkylating agents on early steps of Junin virus multiplication.

Arch. Virol. 143(7) , 1425-32, (1998)

The action of reducing, oxidizing and thiol-alkylating agents on early steps of Junin virus (JV) multiplication in Vero cells was investigated. The presence of reducing agents during virus adsorption as well as incubation of viral particles with these compoun...
