5.1.1.18
Activity 5.1.1.18
Description Serine racemase
Notes Validated eukaryotic enzymes (from metazoa and plants) are similar in sequence to serine ammonia-lyases (4.3.1.17), and in fact they often catalyze dehydration of serine to pyruvate in addition to serine racemization.

In bacteria amino acid racemization is usually carried out by fold-type III enzymes (that we have grouped in the 5.1.1.1 family).
One bacterial enzyme with a sequence similar to those herein and showing some serine racemase activity (WP_013961474 from Roseobacter litoralis; see Kubota et al. 2016, Microbiology 162 53-61) is probably acting physiologically as an erythro-3-hydroxy-D-aspartate ammonia-lyase (family bhcb), as suggested by the genomic context.
