Cloning and characterization of cytidine monophosphate-3-deoxy-d-manno-octulosonate synthetase from Arabidopsis thaliana

J Biosci Bioeng. 2009 Dec;108(6):527-9. doi: 10.1016/j.jbiosc.2009.05.022.

Abstract

The function and metabolic pathway of 3-deoxy-d-manno-octulosonate (KDO) are unclear in plants although it is an essential component in plant cell wall. Here we cloned and characterized a putative Arabidopsis thaliana cytidine monophosphate-KDO synthetase to understand synthetic pathways of KDO. It showed a ubiquitous expression, the activity at an optimal pH of 8.0, and a requirement of Mg2+.
