Abstract excerpt

Anabaena sp. strain PCC 7120 is a filamentous cyanobacterium that can fix N2 in differentiated cells called heterocysts. The products of Anabaena open reading frames (ORFs) all1046, all1047, all1284, alr1834 and all2912 were identified as putative elements of a neutral amino acid permease. Anabaena mutants of these ORFs were strongly affected (1-12% of the wild-type activity) in the transport of Pro, Phe, Leu and...
