CC -!- FUNCTION: Metallopeptidase that binds to the auxin transport inhibitor
CC N-1-naphthylphthalamic acid (NPA). Required for embryonic and seedling
CC development as well as cell cycle progression. Homodimerization is
CC required to proper localization and activity. May play a negative role
CC in the regulation of PIN auxin transport proteins.
CC {ECO:0000269|PubMed:11891249, ECO:0000269|PubMed:19531600,
CC ECO:0000269|PubMed:20154099, ECO:0000269|PubMed:23065197}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Release of an N-terminal amino acid, Xaa-|-Yaa- from a
CC peptide, amide or arylamide. Xaa is preferably Ala, but may be most
CC amino acids including Pro (slow action). When a terminal hydrophobic
CC residue is followed by a prolyl residue, the two may be released as
CC an intact Xaa-Pro dipeptide.; EC=3.4.11.2;
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000269|PubMed:11891249};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000269|PubMed:11891249};
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC Vmax=59 nmol/min/mg enzyme for Tyr-aminofluoromethylcoumarin
CC {ECO:0000269|PubMed:11891249};
CC Vmax=35 nmol/min/mg enzyme for Ala-aminofluoromethylcoumarin
CC {ECO:0000269|PubMed:11891249};
CC Vmax=18 nmol/min/mg enzyme for Pro-aminofluoromethylcoumarin
CC {ECO:0000269|PubMed:11891249};
CC -!- SUBUNIT: Homodimer. Interacts with N-1-naphthylphthalamic acid (NPA).
CC {ECO:0000269|PubMed:20154099}.
CC -!- SUBCELLULAR LOCATION: Membrane; Peripheral membrane protein. Microsome
CC membrane; Peripheral membrane protein. Cytoplasm. Note=The dileucine
CC internalization motif may be involved in intracellular sequestration.
CC -!- TISSUE SPECIFICITY: Ubiquitous with preferential expression in 5 days-
CC old seedlings, roots, young flowers, upper inflorescence stems, and
CC rosette leaves. {ECO:0000269|PubMed:11891249,
CC ECO:0000269|PubMed:19531600}.
CC -!- DEVELOPMENTAL STAGE: Expression starts at 3 days and peaks at 5 days.
CC After, expression levels remain constant from 7 to 10 days. During
CC embryogenesis, expressed first at the site of root meristem formation,
CC then in the epidernal and ground tissue, root meristem and suspensor.
CC In the mature embryo, expressed in the vascular primordia throughout
CC the hypocotyl/root axis. {ECO:0000269|PubMed:11891249,
CC ECO:0000269|PubMed:19531600}.
CC -!- DOMAIN: Dileucine motif seems to be involved in protein-protein
CC interactions.
CC -!- DISRUPTION PHENOTYPE: Loss-of-function mutants show irregular,
CC uncoordinated cell divisions throughout embryogenesis, affecting the
CC shape and number of cotyledons and the hypophysis, and is seedling
CC lethal at 5 days after germination due to root growth arrest. Quiescent
CC center and cell cycle markers show no signals in apm1-1 knockdown
CC mutants, and the ground tissue specifiers SHORTROOT and SCARECROW are
CC misexpressed or mislocalized. apm1 mutants have multiple, fused
CC cotyledons and hypocotyls with enlarged epidermal cells with cell
CC adhesion defects. apm1 alleles show defects in gravitropism and auxin
CC transport. {ECO:0000269|PubMed:19531600}.
CC -!- SIMILARITY: Belongs to the peptidase M1 family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=BAD94901.1; Type=Erroneous initiation; Note=Truncated N-terminus.; Evidence={ECO:0000305};
