Dear CCLrs,

Does anyone know where to find tables of data relevant to different proteins,
namely diffusion coefficients, extinction coefficients and isoelectric points?

More specifically, my questions are:

What is the diffusion coefficient (in aquoeus solutions) for these proteins?
What is their extinction coefficients (at 280 nm)?
What is the isoelectric point for Catalase?
