Figure 1From: Molecular phylogenetics and comparative modeling of HEN1, a methyltransferase involved in plant microRNA biogenesisPrimary structure of A. thaliana HEN1. Domains homologous to known protein families are indicated by color boxes. The unassigned region (with no detectable homology to other families or structures) is indicated by a question mark. Dashed lines indicate the region of predicted disorder.Back to article page
