Immobilized Papain (Agarose Resin)
Immobilized Papain is convenient for producing Fab and Fc fragments from a variety of IgG species. Papain is a nonspecific, thiol-endopeptidase that has a sulfhydryl group in the active site, which must be in the reduced form for activity. When IgG molecules are incubated with papain in the presence of cysteine, one or more peptide bonds in the hinge region are split, producing three fragments of similar size: two Fab fragments and one Fc fragment. The Fc fragments can be separated from the Fab fragments using immobilized Protein A or by ion exchange chromatography. The 50,000Da Fc fragment is often used for determining specificity of the Fc receptors without interference fr... of fragments without contamination of the final preparation with enzyme. Immobilization increases enzyme stability against heat denaturation and autolysis and results in longer maintenance of activity. Cleavage can be regulated via digestion time or flow rate through a column. Immobilized Papain is effective with small volumes of dilute proteins and yields reproducible digests. Group: Enzymes.

isoleucine N-monooxygenase
A heme-thiolate protein (P-450). This enzyme catalyses two successive N-hydroxylations of L-isoleucine, the first committed steps in the biosynthesis of the cyanogenic glucoside lotaustralin in the plant Lotus japonicus.

Ubiquitin-conjugating enzymes perform the second step in the ubiquitination reaction that targets a protein for degradation via the proteasome. The ubiquitination process covalently attaches ubiquitin, a short protein of 76 amino acids, to a lysine residue on the target protein. Once a protein has been tagged with one ubiquitin molecule, additional rounds of ubiquitination form a polyubiquitin chain that is recognized by the proteasome's 19S regulatory particle, triggering the ATP-dependent unfolding of the target protein that allows passage into the proteasome's 20S core particle, where proteases degrade the target into short peptide fragments for recycling by the cell. Applications: Ubiquitin conjugating enzyme fractions mammalian may be used in transferring the activated ubiquitin from e1 to the substrate through an additional high energy thiol ester intermediate e2-s-ubiquitin. ubiquitin-conjugating enzymes, also known as e2 enzymes and more rarely as ubiquitin-carrier enzymes, perform the second step in the ubiquitination reaction that targets a protein for degradation via the proteasome.

A heme-thiolate protein (P-450).
