The cysteine‐free single mutant C32S of APEX2 is a highly expressed and active fusion tag for proximity labeling applications

Meng‐Sen Huang, Wen‐Ching Lin, Jen‐Hsuan Chang, Cheng‐Hung Cheng, more

APEX2, an engineered ascorbate peroxidase for high activity, is a powerful tool for proximity labeling applications. Owing to its lack of disulfides and the calcium‐independent activity, APEX2 can be applied intracellularly for targeted electron microscopy imaging or interactome mapping when fusing to a protein of interest. However, APEX2 fusion is often deleterious to the protein expression, which...

Chien-Hong Lin, Yi-Hsing Yeh, Wen-Ching Lin, Ming-Chien Yang

Colloids and Surfaces B: Biointerfaces > 2014 > 123 > C > 986-994

A silicone-based hydrogel was synthesized from poly(dimethylsiloxane) dialkanol (PDMS), isophorone diisocyanate (IPDI), 2-hydroxyethyl methacrylate (HEMA) and poly(ethylene glycol) methacrylate (PEGMA). The hydrophilicity of the resulting block copolymer was adjustable by manipulating the ratio of PDMS and PEGMA. The results showed that higher PEGMA content led to a lower water contact angle, higher...

In this paper, we reformulated the conventional iterative division algorithm by substituting the pre-defined variable and then updating its initial value accordingly. The reformulated division algorithm allows a restructuring of the divider architecture to further improve its operating speed without increasing latency and area cost. Using the proposed fast algorithm, we developed a high-speed bit-serial...

We identified a spontaneously generated mutant from Synechocystis sp. PCC6803 wild-type cells grown in BG-11 agar plates containing 5 mM Glu and 10 μM DCMU. This mutant carries an R7L mutation on the α-subunit of cyt b559 in photosystem II (PSII). In the recent 2.9 Å PSII crystal structural model, the side chain of this arginine residue is in close contact with the heme propionates of cyt b559. We...

2008 International Conference on Embedded Software and Systems

Realizing AES in hardware faces increasingly more stringent demands for low cost as well as resisting power attacks. For security consideration, countermeasure power analysis approaches to mask sensitive data are needed. The algebraic masking method to protect AES against power attacks is based on various representations of underlying finite fields. However, implementing the transfer matrices between...
