CC -!- FUNCTION: Catalyzes the post-translational formation of 4-
CC hydroxyproline in -Xaa-Pro-Gly- sequences in proline-rich peptide
CC sequences of plant glycoproteins and other proteins. Hydroxyprolines
CC are important constituent of many plant cell wall glycoproteins such as
CC extensins, hydroxyproline-rich glycoproteins, lectins and
CC arabinogalactan proteins. Possesses high affinity for leucine-rich
CC repeat and proline-rich extensins of root cell walls that are essential
CC for root hair development. Hydroxyprolines define the subsequent O-
CC glycosylation sites by arabinosyltransferases which elongate the O-
CC arabinosides on extensins. Has low affinity for the substrates tested
CC in vitro. {ECO:0000269|PubMed:15528200, ECO:0000269|PubMed:21680836}.
