S-adenosyl-l-methionine decarboxylase leader peptide This family consists of the S-adenosyl-l-methionine decarboxylase (AdoMetDC) leader peptides. AdoMetDC is a key regulatory enzymes in the biosynthesis of polyamines. All expressed plant AdoMetDC mRNA 5' leader sequences contain a highly conserved pair of overlapping upstream ORFs (uORFs) that overlap by one base. Sequences of the small uORFs are highly conserved between monocot, dicot and gymnosperm AdoMetDC mRNA species, suggesting a translational regulatory mechanism. |
