Application
Methoxypolyethylene glycol maleimide (MeO-PEG-Mal) is used as a protein pegylation reagent. PEGylation is the process of covalently attaching polyethylene glycol (PEG) polymer chains to other molecule such as proteins.

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

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
