We describe an efficient SCHEMA recombination-based
approach for screening homologous enzymes to identify
stabilizing amino acid sequence blocks. This approach
has been used to generate active, thermostable cellobiohy-
drolase class I (CBH I) enzymes from the 390 625 poss-
ible chimeras that can be made by swapping eight blocks
