Comment: Ga0059261_2711 (A0A1L6J6Q3) from Sphingomonas koreensis DSMZ 15582 is distant from characterized homoserine dehydrogenases and is confirmed by fitness data. BT2403 from Bacteroides thetaiotaomicron (Q8A541_BACTN) is a fusion of aspartate kinase and homoserine dehydrogenase. The homoserine dehydrogenase portion is somewhat diverged. Its role is confirmed by strong cofitness with threonine synthase (the defined media for B. thetaiotaomicron included methionine). DvMF_1412 from Desulfovibrio vulgaris Miyazaki F (B8DRS3_DESVM) is a somewhat diverged homoserine dehydrogenase; it has auxotrophic phenotypes. A0A168MV81 from Brevundimonas is a somewhat diverged homoserine dehydrogenase (fused to aspartate kinase); it has auxotrophic phenotypes.
