CC   -!- FUNCTION: Catalyzes the degradation of 2,5-dichloro-2,5-cyclohexadiene-
CC       1,4-diol (2,5-DDOL) into 2,5-dichlorohydroquinone (2,5-DCHQ) in vitro.
CC       LinX appears not to be involved in gamma-hexachlorocyclohexane (gamma-
CC       HCH) degradation pathway, in contrast to LinC which has the same
CC       enzymatic activity. {ECO:0000250|UniProtKB:D4Z260}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2,5-dichlorocyclohexa-2,5-dien-1,4-diol + NAD(+) = 2,5-
CC         dichlorohydroquinone + H(+) + NADH; Xref=Rhea:RHEA:15741,
CC         ChEBI:CHEBI:15378, ChEBI:CHEBI:27545, ChEBI:CHEBI:28975,
CC         ChEBI:CHEBI:57540, ChEBI:CHEBI:57945;
CC         Evidence={ECO:0000250|UniProtKB:D4Z260};
CC   -!- SIMILARITY: Belongs to the short-chain dehydrogenases/reductases (SDR)
CC       family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=APL96346.1; Type=Erroneous initiation; Note=Truncated N-terminus.; Evidence={ECO:0000305};
