Updated annotation (from data): nitrite transporter, HPP family Rationale: Specifically important in nitrogen source Sodium nitrite. Related to Synpcc7942_1745, which can be a nitrite uptake transporter (PMID:24904028). Besides the HPP domain, it encodes two cytoplasmic CBS domains, which might play a regulatory role. Original annotation: CBS domain protein Type 1: Protein-coding gene Located on scaffold AE015451, + strand, nucleotides 2,679,260 to 2,680,414 See nucleotide sequence around PP_2349 or for all of scaffold AE015451
