摘要:
The present invention provides compositions comprising peptidyl inhibitors of CD40L-dependent signaling that are not derived from a natural binding partner of CD40L such as CD40, or from a native CD40-CD40L interface. More particularly, the peptidyl inhibitors of the present invention are derived from natural sources that do not express CD40-Cd40L costimulatory pathways. The invention also provides synthetic derivatives and analogs of the peptidyl inhibitors having enhanced binding affinity for CD40L or enhanced inhibitory activity relative to their parent molecules.

摘要:
The invention provides polynucleotides, preferably synthetic polynucleotides, which encode processing enzymes that are optimized for expression in plants. The polynucleotides encode mesophilic, thermophilic, or hyperthermophilic processing enzymes, which are activated under suitable activating conditions to act upon the desired substrate. Also provided are “self-processing” transgenic plants, and plant parts, e.g., grain, which express one or more of these enzymes and have an altered composition that facilitates plant and grain processing. Methods for making and using these plants, e.g., to produce food products having improved taste and to produce fermentable substrates for the production of ethanol and fermented beverages are also provided.
