Defects in hydrolyzing phosphoUb chains A Structure of USP2 (red) bound to Ub (cyan) [pdb‐id 2hd5 (Renatus et al, )], with a close‐up on Ub Ser65 in the distal Ub.Figure 8A Structure of USP2 (red) bound to Ub (cyan) [pdb‐id 2hd5 (Renatus et al, )], with a close‐up on Ub Ser65 in the distal Ub. A negative charge at the USP2 Asp345 position is conserved in most USP enzymes (Ye et al, ). B-H Ubiquitination reactions from Fig A were used as input for deubiquitinase (DUB) analysis. Silver stained time course gels are shown. All DUBs tested (USP2, USP8, USP15, USP30, Ataxin‐3, USP21) hydrolyze Ub chains but have significantly lower activity against phosphoUb chains, with the exception of vOTU and USP21. B-H Ubiquitination reactions from Fig A were used as input for deubiquitinase (DUB) analysis. Silver‐stained time‐course gels are shown. All DUBs tested (USP2, USP8, USP15, USP30, Ataxin‐3, USP21) hydrolyze Ub chains but have significantly lower activity against phosphoUb chains, with the exception of vOTU and USP21. I USP30 activity was significantly lower for cIAP polyUb as compared to other USP DUBs. Cleavage assays against the diUb panel reveals preference for Lys6‐linked chains. J USP30 activity is decreased against phosphorylated Lys6 diUb. K-N Deubiquitinase assays against phosphorylated tetraUb. The activity of AMSH (K), TRABID (L), OTUB1 (M) and OTULIN (N) are inhibited with Lys63, Lys33, Lys48 and Met1 phosphorylated tetraUb, respectively.
Figure 8Under Fe deficient conditions, MdCAX3 mRNA is continuously transported from leaves to the roots through the phloem, and is translated in the roots to proteins that pump zinc ions into vacuoles for partition detoxification. This relieves the degradation of MdIRT1 induced by excessive Zn levels and promotes the PM H+-ATPase to pump protons to the apoplast to promote rhizosphere acidification. In Mb, the process is hampered by the lack of MdCXIP1.
