Description
Description
The S1A family of peptidases comprises serine proteases and the non-catalytic serine protease homologs belonging to MEROPS peptidase family S1, subfamily A. They play essential roles in a wide range of insect physiological processes including digestion, defense and development. (Adapted from FBrf0240739.)
Notes on Group

The membership of and classifications within the PEPTIDASE FAMILY S1A group generally follows the analysis of Cao and Jiang 2018 (FBrf0240739), which was improved and updated compared to previous analyses (Ross et al. 2003 (FBrf0155784), Shah et al. 2008 (FBrf0202030), Veillard et al 2016 (FBrf0230906), MEROPS database (FBrf0239469)).
