| Name | ectoine biosynthesis | |
| Type | PATHWAY | |
| Description | Ectoine is a compatible solute used as an osmoprotectant by a number of bacterial species, including Vibrio cholerae, Halomonas variabilis, Bacillus pasteurii, etc. Key enzymes are diaminobutyric acid acetyltransferase (EctA), diaminobutyric acid aminotransferase (EctB), and ectoine synthase (EctC). Ectoine is 1,4,5,6-tetrahydro-2-methyl-4-pyrimidinecarboxylic acid. | |
