  • Patent number: 8853360
    Abstract: An isolated polypeptide comprising a botulinum neurotoxin C1 light chain having a modified amino acid sequence relative to the sequence of a wild-type botulinum neurotoxin C1 light chain is disclosed. The modified botulinum neurotoxin C1 light chain is capable of selectively cleaving syntaxin protein, but has substantially reduced or no activity against SNAP-25 as compared to wild type botulinum neurotoxin C1 light chain, and is thus useful as a research tool and in medical treatment.

  • Patent number: 7203919
    Abstract: Methods and apparatus for retiming an integrated circuit are described. According to certain embodiments, the retiming comprises performing a timing analysis for one or more paths in the integrated circuit to obtain slack values, selecting one of the paths based on the slack values obtained, and determining a retimeable cut along the path selected. The retimeable cut in these exemplary embodiments comprises a set of input pins for one or more logic instances in the integrated circuit to which one or more retimed sequential elements can be coupled in order to improve the slack value of the path selected. In particular embodiments, the retimeable cut is automatically selected from multiple possible cuts along the path selected. Other embodiments for retiming integrated circuits are disclosed, as well as integrated circuits and circuit design databases retimed by the disclosed methods. Computer-executable media storing instructions for performing the disclosed methods are also disclosed.
