The E2 enzymes are key enzymes in the ubiquitin and ubiquitin-like protein ligation pathways. To understand the functionality of the different E2 enzymes, we analyzed 190 protein sequences and 211 structures and electrostatic potentials. Key findings include: The ScUbc1 orthologs are defined by a C-terminal UBA domain. An N-terminal sequence motif that is(More)
Post-translational modification by ubiquitin and ubiquitin-like (UBL) proteins is a key mechanism for cellular control. The specificity of the enzymes of ubiquitination and their close paralogs is dependent on their molecular electrostatic potentials. For example, analysis of molecular electrostatic potentials and electrostatically key residues can account(More)
In tobacco, the heavy metal P1B-ATPases HMA4.1 and HMA4.2 function in root-to-shoot zinc and cadmium transport. We present greenhouse and field data that dissect the possibilities to impact the two homeologous genes in order to define the best strategy for leaf cadmium reduction. In a first step, both genes were silenced using an RNAi approach leading to(More)
