Interaction of pepsin with aromatic amino acids and their derivatives immobilized to Sepharose.

Jana Frýdlová et al.

Journal of chromatography. B, Analytical technologies in the biomedical and life sciences, 863(1), 135-140 (2008-02-08)

The interaction of porcine pepsin A with immobilized derivatives of aromatic amino acids was investigated. Divinyl sulfone-activated Sepharose was used to immobilize N-acetyl-l-phenylalanine and 3,5-diiodo-l-tyrosine via their free carboxyl groups and l-tyrosine via its amino group. Immobilized l-tyrosine was iodinated

Identification and quantitation of iodotyrosines and iodothyronines in hydrolysate of iodinated casein by capillary electrophoresis.

Yining Zheng et al.

Talanta, 69(1), 107-112 (2008-10-31)

In this paper, a new method for separation, identification and quantitation of iodotyrosines and iodothyronines [3-monoiodo-L-tyrosine (MIT), 3,5-diiodo-L-tyrosine (DIT), L-thyronine (T(0)), 3,5-diiodo-L-thyronine (T(2)), 3,5,3'-triiodo-L-thyronine (T(3)) and 3,3',5,5'-tetraiodo-L-thyronine (T(4))] was described by using capillary electrophoresis with photodiode-array ultraviolet-visible detection (CE-UV). The

Chiral discrimination of D- and L-amino acids using iodinated tyrosines as chiral references: effect of iodine substituent.

Sangeeta Kumari et al.

Journal of the American Society for Mass Spectrometry, 18(8), 1516-1524 (2007-06-26)

L-Tyrosine and iodinated L-tyrosines, i.e., 3-iodo-L-tyrosine and 3,5-diiodo-L-tyrosine, are successfully used as chiral references for the chiral discrimination of aliphatic, acidic, and aromatic amino acids. Chiral discrimination is achieved by investigating the collision-induced dissociation spectra of the trimeric complex [Cu(II)(ref)(2)(A)
