CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000256|ARBA:ARBA00001933};
CC -!- PATHWAY: Amino-acid biosynthesis; L-isoleucine biosynthesis; 2-
CC oxobutanoate from L-threonine: step 1/1.
CC {ECO:0000256|ARBA:ARBA00004810}.
CC -!- PATHWAY: Amino-acid degradation; L-threonine degradation via propanoate
CC pathway; propanoate from L-threonine: step 1/4.
CC {ECO:0000256|ARBA:ARBA00004958}.
CC -!- SUBUNIT: In the native structure, TdcB is in a dimeric form, whereas in
CC the TdcB-AMP complex, it exists in a tetrameric form (dimer of dimers).
CC {ECO:0000256|ARBA:ARBA00011447}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
