Entry
ecob00260                   Pathway                                
Name
Glycine, serine and threonine metabolism - Escherichia coli B C3029
Description
Serine is derived from 3-phospho-D-glycerate, an intermediate of glycolysis [MD:M00020], and glycine is derived from serine. Threonine is an essential amino acid, which animals cannot synthesize. In bacteria and plants, threonine is derived from aspartate [MD:M00018].
Class
