Abstract:

Serine carboxypeptidases (SCP) widely exist in animals, plants and fungi and form a large protease family. This review briefly introduces the structural characteristics and classification of SCP and serine carboxy-peptidase-like proteins (SCPLs), and summarizes the current research advances of SCP/SCPLs in their subcel-lular localization, gene expression, the regulatory role in stress tolerance, cellular regulation and synthesis of plant secondary metabolites.

Key words: serine carboxypeptidase; gene expression regulation; secondary metabolites; stress tolerance
