Site-specific mono-PEGylations were performed in different conformational regions of Thymosin alpha 1 (T alpha 1) by introducing one cysteine residue into the chosen site and coupling with thiol-specific mPEG-MAL reagent. Results demonstrated that PEGylated sites and regions influenced the conformations

We have modified recombinant interleukin-2 (rIL-2) to facilitate site-directed covalent attachment of monomethoxy polyethylene glycol (PEG). The site chosen for modification and subsequent covalent attachment with PEG (PEGylation) was the single glycosylation position found in the native interleukin-2 (IL-2). The

The design of the extension arm-facilitated PEGylation (EAFP) of proteins takes advantage of the high selective and quantitative aspects of the thiol-maleimide reaction. However, the efficiency of EAFP with hemoglobin varied with the batches of maleimide-PEG. The low level of

Disulfide bond formation is crucial for the biogenesis and structure of many proteins that are localized in the intermembrane space of mitochondria. The importance of disulfide bond formation within mitochondrial proteins was extended beyond soluble intermembrane space proteins. Tim22, a

Polyprenol phosphate phosphoglycosyl transferases (PGTs) catalyze the first membrane-committed step in assembly of essential glycoconjugates. Currently there is no structure-function information to describe how monotopic PGTs coordinate the reaction between membrane-embedded and soluble substrates. We describe the structure and mode
