Fig 2. AtGLYI2 is Zn2+ dependent while AtGLYI3 and AtGLYI6 are Ni2+ dependent GLYI.

Fig 2

(A) Histogram depicting activity of purified AtGLYI2 protein in presence of various metal ions. AtGLYI2 was demetalled using EDTA and then, reconstituted with different metal ions. The activity was checked after 2 h and 4 h of reconstitution. AtGLYI2 showed maximal activity with MnCl2 followed by CoCl2, NiCl2 and CdCl2. This behavior is characteristic of Zn2+ dependent GLYI enzymes. (B) Histogram depicting activity of purified AtGLYI3 and AtGLYI6 in presence and absence of Ni2+. (C) Histogram depicting activity of thrombin cleaved and purified AtGLYI3 and AtGLYI6 (to remove His tag) in presence and absence of Ni2+.
