FEATURES

FAMILY

class-II aminoacyl-tRNA synthetase family

DESCRIPTION

Also known as SYP_PLAF7, proRS. Catalyzes the attachment of proline to tRNA(Pro) in a two-step reaction: proline is first activated by ATP to form Pro-AMP and then transferred to the acceptor end of tRNA(Pro) (By similarity). Functions in trans to edit the amino acid moiety from incorrectly charged Ala-tRNA(Pro). Has no activity on correctly charged Pro-tRNA(Pro) or Ala-tRNA(Ala). Homodimer.
