Fig. 1. Schematic of the domain structure of CaBni1p and CaBnr1p. The functional domains of CaBni1p and CaBnr1p and their boundaries were identified and defined using the SMART program and alignment with ScBni1p and ScBnr1p sequences. The amino acid (aa) identity (%) of the corresponding domains between CaBni1p and ScBni1p and between CaBnr1p and ScBnr1p is given below each domain.
