Studies on chemically aggregated pepsin using glutaraldehyde.

Biotechnology and bioengineering

Khan SS, Siddiqi AM.
PMID: 18553688
Biotechnol Bioeng. 1985 Apr;27(4):415-9. doi: 10.1002/bit.260270405.

Porcine pepsin was immobilized by chemical aggregation using glutaraldehyde as a bifunctional crosslinking agent. The immobilized pepsin followed Michaelis-Menten kinetics (K(m) = 5.3 x 10(-5) M) and the yield of immobilization was 91%. The activation energy of the immobilized...

Radical Rearrangement Chemistry in Ultraviolet Photodissociation of Iodotyrosine Systems: Insights from Metastable Dissociation, Infrared Ion Spectroscopy, and Reaction Pathway Calculations.

Journal of the American Society for Mass Spectrometry

Ranka K, Zhao N, Yu L, Stanton JF, Polfer NC.
PMID: 29845561
J Am Soc Mass Spectrom. 2018 Sep;29(9):1791-1801. doi: 10.1007/s13361-018-1959-1. Epub 2018 May 29.

We report on the ultraviolet photodissociation (UVPD) chemistry of protonated tyrosine, iodotyrosine, and diiodotyrosine. Distonic loss of the iodine creates a high-energy radical at the aromatic ring that engages in hydrogen/proton rearrangement chemistry. Based on UVPD kinetics measurements, the...

Serum diiodotyrosine - a biomarker to differentiate destructive thyroiditis from Graves' disease.

European journal of endocrinology

Fujita N, Ono Y, Sano A, Kimata M, Oyama S, Hashimoto K, Sato I, Kudo M, Miyashiro Y, Fujikata A, Tanaka Y.
PMID: 34874894
Eur J Endocrinol. 2022 Jan 06;186(2):245-253. doi: 10.1530/EJE-21-0901.

OBJECTIVE: Conventional diagnostic methods are limited in their ability to differentiate destructive thyroiditis from Graves' disease. We hypothesised that serum diiodotyrosine (DIT) and monoiodotyrosine (MIT) levels could be biomarkers for differentiating destructive thyroiditis from Graves' disease.DESIGN: Patients with destructive...

The structure of natively iodinated bovine thyroglobulin.

Acta crystallographica. Section D, Structural biology

Kim K, Kopylov M, Bobe D, Kelley K, Eng ET, Arvan P, Clarke OB.
PMID: 34726172
Acta Crystallogr D Struct Biol. 2021 Nov 01;77:1451-1459. doi: 10.1107/S2059798321010056. Epub 2021 Oct 29.

Thyroglobulin is a homodimeric glycoprotein that is essential for the generation of thyroid hormones in vertebrates. Upon secretion into the lumen of follicles in the thyroid gland, tyrosine residues within the protein become iodinated to produce monoiodotyrosine (MIT) and...

A QUANTITATIVE THEORY OF THE PRECIPITIN REACTION : VI. THE REACTION BETWEEN MAMMALIAN THYROGLOBULINS AND ANTIBODIES TO HOMOLOGOUS AND HETEROLOGOUS PREPARATIONS.

The Journal of experimental medicine

Stokinger HE, Heidelberger M.
PMID: 19870659
J Exp Med. 1937 Jul 31;66(2):251-72. doi: 10.1084/jem.66.2.251.

1. Quantitative data for both homologous and heterologous precipitin reactions of human, hog, beef, and sheep thyroglobulins show that these reactions have the same mechanism as other instances of the precipitin reaction and may be expressed quantitatively by the...
