Cystathionine γ-synthase (MetB) condenses O-acetyl-l-homoserine (OAHS) or O-succinyl-l-homoserine (OSHS) with cysteine to produce cystathionine. To investigate the molecular mechanisms and substrate specificity of MetB from Corynebacterium glutamicum (CgMetB), we determined its crystal structure at

Cystathionine gamma-synthase (CGS) is a key enzyme of Met biosynthesis in bacteria and plants. Aligning the amino acid sequences revealed that the plant enzyme has an extended N-terminal region that is not found in the bacterial enzyme. However, this region is not essential for the catalytic
The level of threonine in tobacco seeds is limited by substrate availability, while the level of methionine is limited also by the activity of cystathionine γ-synthase.

Methionine and threonine are two essential amino acids whose low levels limit the nutritional quality of seeds. The current objective was to define factors that regulate and might increase their levels in seeds. Feeding experiments carried out on receptacles of developing tobacco (Nicotiana tabacum)

The pyridoxal 5'-phosphate-dependent enzyme cystathionine beta-lyase (CBL) catalyzes the penultimate step in the de novo biosynthesis of Met in microbes and plants. Absence of CBL in higher organisms makes it an important target for the development of antibiotics and herbicides. The
