... and OntoNotes (Hovy et al., 2006). Clearly, as one moves towards a more application- and domain- driven idea of ‘correct’ tokenization, a more trans- parent, flexible, and adaptable approach to ... decades. Ap- proximately, this means splitting off punctuation into separate tokens, disambiguating straight quotes, and separating contractions such as can’t into ca and n’t. There are, howev...

... intimate van der Waals packing (like a jigsaw puzzle) [13]. The problem can therefore be framed simply: we need a way to (a) make large numbers of variants of proteins and (b) to analyze them rapidly ... [74–76]. Chorismate mutase is thought to catalyze a Claisen condensation principally by binding chorismate in a conformation that favors the pericyclic reaction and allows trans...

... members of the ADAM family have been shown to act as a- secretase [8,36,37]: ADAM9, ADAM10 and ADAM17 (TACE). Overexpression of ADAM9 has been reported to increase the basal and protein kinase C (PKC) ... mecha- nism: ADAM9 has been shown to proteolytically pro- cess ADAM10 [40–42]. By contrast to ADAM9, ADAM10 was found to have constitutive and regu- lated a- secretase activity a...

In addi- tion, CBP contains a number of protein-binding domains that mediate transcription ... CBP is a structural platform that is capable of binding several different families of transcriptional activators [30], and evidence indicates that the KIX domain has the ability to...

Both the PDI a domain and DsbA have a catalytic site, with an associated substrate-binding site, but lack an inde- pendent ... rhodanese was also decreased by bacitracin. The decrease in the noncatalyzed rate (31%) was similar to that of the PDI-catalyzed reaction (a 32% decrease). These results Fig. 1...
