Peptidase family S64 This family of fungal proteins is involved in the processing of membrane bound transcription factor Stp1. The processing causes the signalling domain of Stp1 to be passed to the nucleus where several permease genes are induced. The permeases are important for uptake of amino acids, and processing of tp1 only occurs in an amino acid-rich environment. This family is predicted to be distantly related to the trypsin family (MEROPS:S1) and to have a typical trypsin-like catalytic triad. |
