Sequence Comparison of the Proteins AtSFR2, TaBGLY, and TspBGLU.
TaBGLY (Thermococcus sp β-glycosidase) and TspBGLU (Thermosphaera aggregans β-glucosidase) represent the closest protein homologs of defined function available in public databases. The family 1 glycosyl hydrolase motif (TFNEP, I/VTENG) is shown (*). The position of the changed amino acid in sfr2-1 (G to D) and the predicted site of early translation termination in sfr2-i2 are also indicated. Black, identical or gonnet350 substitution values of 15 or more; gray, Gonnet350 substitution values of 5 to 14.
