The 20 kDa Bacillus circulans Bcx is a well-studied endoxylanase with a β-jellyroll fold that
places its N-and C-termini in salt bridge contact. Initial experiments verified that Bcx could be …

Diaminopropionate ammonia-lyase transforms D and L isomers of 2, 3-diaminopropionate to
pyruvate and ammonia. It catalyzes D-and l-serine less effectively. L-2, 3-diaminopropionate …

Protein‐splicing domains are frequently used engineering tools that find application in the in
vivo and in vitro ligation of protein domains. Directed evolution is among the most promising …

Development and marketing of new drugs require stringent validation that are expensive
and time consuming. Non-invasive multimodality molecular imaging using reporter genes …

Proteins are inherently flexible and structurally dynamic biomolecules. The ability to switch
between different conformational state s is often a pivotal feature for such diverse cellular …
