We have determined a 2.6A resolution crystal structure of Pfu DNA polymerase, the most commonly used high fidelity PCR enzyme, from Pyrococcus furiosus. Although the structures of Pfu and KOD1 are highly similar, the structure of Pfu elucidates the electron density of the interface between the exonuclease and thumb domains, which has not been previously(More)
Glutaryl 7-aminocephalosporanic acid acylase (GCA, EC is a member of N-terminal nucleophile (Ntn) hydrolases. The native enzyme is an (alpha beta)(2) heterotetramer originated from an enzymatically inactive precursor of a single polypeptide. The activation of precursor GCA consists of primary and secondary autoproteolytic cleavages, generating a(More)
Vascular enlargement is a characteristic feature of angiopoietin-1 (Ang1)-induced changes in adult blood vessels. However, it is unknown whether tissues having Ang1-mediated vascular enlargement have more blood flow or whether the enlargement is reversible. We have recently created a soluble, stable and potent Ang1 variant, COMP-Ang1. In the present study,(More)
Biomarkers enable early diagnosis, guide molecularly targeted therapy and monitor the activity and therapeutic responses across a variety of diseases. Despite intensified interest and research, however, the overall rate of development of novel biomarkers has been falling. Moreover, no solution is yet available that efficiently retrieves and processes(More)
