Dear Midori,

    once again there is a problem related to the dbxref of the term with 
id: GO:0009703 :

id: GO:0009703
name: nitrate reductase (NADH) activity
namespace: molecular_function
def: "Catalysis of the reaction: NO2- (nitrite) + NAD+ + H2O = NO3- 
(nitrate) + NADH + H+." [EC:]
comment: Note that this function was formerly EC:
exact_synonym: "assimilatory NADH:nitrate reductase activity" [EC:]
exact_synonym: "NADH-dependent nitrate reductase activity" [EC:]
exact_synonym: "NADH-nitrate reductase activity" [:EC e]
exact_synonym: "NADH:nitrate oxidoreductase activity" [EC:]
exact_synonym: "NADH:nitrate reductase" []
exact_synonym: "nitrate reductase (NADH(2)) activity" [EC:]
broad_synonym: "assimilatory nitrate reductase activity" [EC:]
xref_analog: EC:
is_a: GO:0046857 ! oxidoreductase activity, acting on other nitrogenous 
compounds as donors, with NAD or NADP as acceptor

In particular the dbxref of the third listed synonym (exact_synonym: 
"NADH-nitrate reductase activity" [:EC e]) is wrong. I guess it should 
be EC:
