UniProt entry A0A1J6KEF3 for Nicotiana attenuata QPT_0
-
QPT_0 is a quinolinate phosphoribosyltransferase family enzyme
"DE RecName: Full=nicotinate-nucleotide diphosphorylase (carboxylating)"
-
UniProt places QPT_0 in both NAD and nicotine pathway annotations
"CC -!- PATHWAY: Alkaloid biosynthesis; nicotine biosynthesis."
NaQPT2 QPT_0 candidate notes
-
QPT_0 is a strong biochemical candidate for the duplicated pyridine branch
"UniProt curates A0A1J6KEF3 as nicotinate-nucleotide diphosphorylase (carboxylating), the quinolinate phosphoribosyltransferase/NadC reaction that connects quinolinate metabolism to NAD and nicotine pathway annotations."
-
QPT_0 remains unresolved relative to QPT_1 for pathway specialization
"QPT_0 is therefore a plausible NaQPT2 candidate, but the current public record does not by itself establish whether QPT_0 or QPT_1 is the root nicotine-pathway-specialized paralog."
