Abstract: front page image
(EN)A group of arabinose isomerases are disclosed that provide effective amounts of activity for use of arabinose in production of ethanol, when expressed in yeast cells expressing the other enzymes of an arabinose utilization pathway. The group of arabinose isomerases represents a clade of a phylogenetic tree, having a distinguishing conserved amino acid sequence motif. Other useful arabinose isomerases are also disclosed.
(FR)L'invention concerne un groupe d'arabinoses isomérases qui génèrent des quantités efficaces d'activité pour l'utilisation de l'arabinose dans la production de l'éthanol, quand elles sont exprimées dans des cellules de levures exprimant les autres enzymes d'une voie d'utilisation des arabinoses. Le groupe d'arabinoses isomérases représente un clade d'un arbre phylogénétique, ayant un motif de séquence d'acides aminés conservé distinctif. D'autres arabinoses isomérases utiles sont en outre décrites.
