Updated annotation (from data): nitrite transporter, HPP family Rationale: Important for nitrite stress. This was shown to be capable of nitrite uptake (PMID:24904028), but with moderate affinity, and this data suggests that it might be exporting nitrite. Since nitrate was also present, this could also be a nitrate/nitrite antiporter (speculative). Original annotation: hypothetical protein Type 1: Protein-coding gene Located on scaffold NC_007604, - strand, nucleotides 1,815,848 to 1,816,393 See nucleotide sequence around Synpcc7942_1745 or for all of scaffold NC_007604
