Cloning of two cDNAs encoding a family of ATP sulfurylase from Camellia sinensis related to selenium or sulfur metabolism and functional expression in Escherichia coli

ATP sulfurylase, the first enzyme in the sulfate assimilation pathway of plants, catalyzes the formation of adenosine phosphosulfate from ATP and sulfate. Here we report the cloning of two cDNAs encoding ATP sulfurylase (APS1 and APS2) from Camellia sinensis. They were isolated by RT-PCR and RACE-PC...

520 |a ATP sulfurylase, the first enzyme in the sulfate assimilation pathway of plants, catalyzes the formation of adenosine phosphosulfate from ATP and sulfate. Here we report the cloning of two cDNAs encoding ATP sulfurylase (APS1 and APS2) from Camellia sinensis. They were isolated by RT-PCR and RACE-PCR reactions. The expression of APS1 and APS2 are correlated with the presence of ATP sulfurylase enzyme activity in cell extracts. APS1 is a 1415-bp cDNA with an open reading frame predicted to encode a 360-amino acid, 40.5kD protein; APS2 is a 1706-bp cDNA with an open reading frame to encode a 465-amino acid, 51.8kD protein. The predicted amino acid sequences of APS1 and APS2 have high similarity to ATP sulfurylases of Medicago truncatula and Solanum tuberosum, with 86% and 84% identity respectively. However, they share only 59.6% identity with each other. The enzyme extracts prepared from recombinant Escherichia coli containing Camellia sinensis APS genes had significant enzyme activity
