Expression of the Oenococcus oeni trxA gene is induced by hydrogen peroxide and heat shock

A study was conducted to analyze the nucleotide sequence of a chromosomal DNA fragment encoding the thioredoxin of Oenococcus oeni. The size of the transcript and the transcriptional start site were determined. The expression of the gene in response to oxidative and heat stresses were then analyzed. Experimental results indicated that the trxA gene encodes a functional thioredoxin.
