EC Number Cloned (Comment) Organism
4.2.1.90 the genes for L-rhamnose catabolism RHA1, LRA2, LRA3 and LRA4 but not LADH are clustered, genetic organization, phylogenetic analysis, overview. Functional expression of gene LRA3 in Saccharomyces cerevisiae with a strong constitutive promoter. C-terminally his-tagged protein shows no activity and the activity of the N-terminally tagged protein is reduced by about 95%, so the enzyme is expressed without tagand not purified Scheffersomyces stipitis
