Fig. 6From: Red Sea Atlantis II brine pool nitrilase with unique thermostability profile and heavy metal toleranceEffect of different metal ions on NitraS-ATII activity. The nitrilase activity is retained at high concentrations of Mg2+ and Mn2+ and to a lower extent with Zn2+. A high degree of tolerance is also observed towards Cd2+and Co2+, and to a lower extent towards Ni2+. Inactivation is observed even with low concentrations of Cu2+ and Hg2+ Back to article page
