Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

Involved in strigolactones biosynthesis by cleaving the C(27) 9-cis-10'-apo-beta-carotenal produced by CCD7. Produces the C(19) carlactone and a C8 hydroxyaldehyde. Also shows lower activity with all-trans-10'-apo-beta-carotenal producing a C9 dialdehyde and the C(18) 13-apo-beta-carotenone. Strigolactones are hormones that inhibit tillering and shoot branching through the MAX-dependent pathway, contribute to the regulation of shoot architectural response to phosphate-limiting conditions and function as rhizosphere signal that stimulates hyphal branching of arbuscular mycorrhizal fungi and trigger seed germination of root parasitic weeds.2 Publications

Miscellaneous

The branching phenotypes of the ccd7/max3 and ccd8b/max4 mutants can be rescued by exogenous treatment with the synthetic strigolactone analogs GR24 and 4BD.1 Publication

<p>The checksum is a form of redundancy check that is calculated from the sequence.
