[HTML][HTML] Regulatory Monoubiquitination of Phosphoenolpyruvate Carboxylase in Germinating Castor Oil Seeds*♦
RG Uhrig, YM She, CA Leach, WC Plaxton - Journal of Biological Chemistry, 2008 - ASBMB
Phosphoenolpyruvate carboxylase (PEPC) is a tightly regulated enzyme situated at the core
of plant C-metabolism. Although its anaplerotic role and control by allosteric effectors,
reversible phosphorylation, and oligomerization have been well documented in the
endosperm of developing castor oil seeds (COS), relatively little is known about PEPC in
germinating COS. The initial phase of COS germination was accompanied by elevated
PEPC activity and accumulation of comparable amounts of pre-existing 107-kDa and …
