Abstract

A conserved PGGxGTxxE motif misleads the cytokinin (CK) converting LONELY GUY enzymes to be wrongly annotated as lysine decarboxylases (LDCs). However, so far PGGxGTxxE motif-containing LDCs do not show any LDC activity. Instead, they show phosphoribohydrolase activity by converting inactive CK nucleotides into active free-base forms to invoke CK responses.

Keywords: LOG-family proteins; PGGxGTxxE motif; active cytokinins; cross-kingdom regulation; lysine decarboxylase; phosphoribohydrolase.
