1.2.1.95 | recombinant expression of N-terminally His6-tagged truncated NPS3 enzyme mutant lacking the 247 amino acids of the N-terminal ADA domain from pET21a-based expression plasmid pMR1, recombinant expression of N-terminally His6-tagged truncated NPS3 enzyme mutant lacking the 152 amino acids of the N-terminal ADA domain from expression plasmid pDK22, and recombinant expression of the 102.8 kDa ADA-A didomain (lacking the C-terminal 515 amino acids) and the 75.7 kDa standalone NPS3A domain, respectively, in which the first 247 and terminal 515 amino acids are absent, from plasmids pDK24 and pDK25, both based on expression vector pET28a, all in Escherichia coli strain KRX |
