I would like to know bioinformatic/s tool that can be suitable for the identification of cysteine-rich proteins from set of oomycete effector proteins I have. I want to identify cysteine-rich proteins from this set of proteins and group them according to the content of cysteine residues. Your help would be greatly appreciated!
