the work was aimed at studying enzymes involved in the metabolism of flavin nucleotides , namely , riboflavin kinase ( ec 2.7.1.26 ) and fad pyrophosphorylase ( ec 2.7.7.2 ) , as well as flavin mononucleotide hydrolysis by acid phosphatase ( ec 3.1.3.2 ) and alkaline phosphatase ( ec 3.1.3.1 ) in streptomyces olivaceus actively producing vitamin b12 .
