A major integral protein of the plant plasma membrane binds flavin

Abstract

 Abundant flavin binding sites have been found in membranes of plants and fungi. With flavin mononucleotide-agarose affinity columns, riboflavin-binding activity from microsomes of Cucurbita pepo L. hypocotyls was purified and identified as a specific PIP1-homologous protein of the aquaporin family. Sequences such as gi|2149955 in Phaseolus vulgaris, PIP1b… (More)
