Protein Info for ABZR86_RS15975 in Dyella japonica UNC79MFTsu3.2

Updated annotation (from data): threonine synthase (EC 4.2.3.1)
Rationale: Important for fitness in most defined media. Semi-automated annotation based on the auxotrophic phenotype and a hit to HMM TIGR00260.
Original annotation: threonine synthase

These analyses and tools can help you predict a protein's function, but be skeptical. For enzymes, over 10% of annotations from KEGG or SEED are probably incorrect. For other types of proteins, the error rates may be much higher. MetaCyc and Swiss-Prot have low error rates, but the best hits in these databases are often quite distant, so this protein's function may not be the same. TIGRFam has low error rates. Finally, many experimentally-characterized proteins are not in any of these databases. To find relevant papers, use PaperBLAST.
