Ferguson, Andrew D., Labunskyy , Vyacheslav, Fomenko, Dmitri E., Arac, Demet, Chelliah, Yogarany, Amexcua, Carlos A., ...

Selenium has significant health benefits, including potent cancer prevention activity and roles in immune function and the male reproductive system. Selenium-containing proteins, which incorporate...

A Novel Cysteine-rich Domain of Sep15 Mediates the Interaction with UDP-glucose:Glycoprotein Glucosyltransferase (2005)

Labunskyy, Vyacheslav M., Ferguson, Andrew D., Fomenko, Dmitri E., Chelliah, Yogarany, Hatfield, Dolph L., Gladyshev, Vadim N.

Selenium is an essential trace element with potent cancer prevention activity in mammals. The 15-kDa selenoprotein (Sep15) has been implicated in the chemopreventive effect of dietary selenium....

A Drosophila Pattern Recognition Receptor Contains a Peptidoglycan Docking Groove and Unusual L,D-Carboxypeptidase Activity (2004)

Chung-I Chang, Sébastien Pili-Floury, Mireille Hervé, Claudine Parquet, Yogarany Chelliah, Bruno Lemaitre, ...

The Drosophila protein PGRP-SA is found to have an intrinsic activity to cleave L,D-configured peptide bonds, which exist only in prokaryotes. This work reveals a rare enzymatic activity in a...

Signal transduction pathway of TonB-dependent transporters

Ferguson, Andrew D., Amezcua, Carlos A., Halabi, Najeeb M., Chelliah, Yogarany, Rosen, Michael K., Ranganathan, Rama, ...

Transcription of the ferric citrate import system is regulated by ferric citrate binding to the outer membrane transporter FecA. A signal indicating transporter occupancy is relayed across the outer...

Structural basis for conserved complement factor-like function in the antimalarial protein TEP1

Baxter, Richard H. G., Chang, Chung-I, Chelliah, Yogarany, Blandin, Stéphanie, Levashina, Elena A., Deisenhofer, Johann

Thioester-containing proteins (TEPs) are a major component of the innate immune response of insects to invasion by bacteria and protozoa. TEPs form a distinct clade of a superfamily that includes the...
