Updated annotation (from data): ethanol oxidation regulatory protein ercA Rationale: Specifically important for: Ethanol; D-Trehalose dihydrate. Similar to ercA (PA1991) which apparently has a regulatory role (PMCID: PMC3754586) rather than being directly involved in catabolism. Also this gene is adjacent to an apparent ercS (HP15_3134). Do not see why SEED annotates it as aldehyde dehydrogenase. HP15_3164 is probably the ethanol dehydrogenase and HP15_3144 the acetaldehyde dehydrogenase. Original annotation: iron-containing alcohol dehydrogenase Type 1: Protein-coding gene Located on scaffold CP001978, - strand, nucleotides 3,287,579 to 3,288,742 See nucleotide sequence around HP15_3135 or for all of scaffold CP001978
