Copper is one of the most important trace elements to life. Human HCUTA is
a novel cDNA encoding a 156aa protein, which may participate in human coppe
r tolerance system. The HCUTA protein is highly similar to protein CUT A1 o
f E. coli. The whole opening reading frame of HCUTA cDNA was amplified by P
CR and cloned into pET28a + express vector, and the HCUTA protein was effec
tively expressed in E. coli BL21 (DE3).
