2.3.1.236	expression in Escherichia coli	
2.3.1.236	heterologous expression of aziB in Streptomyces albus. Addition of aziB1 (encoding a P450 hydroxylase) and aziB2 (encoding an O-methyltransferase) to aziB in Streptomyces albus allows for the production of 3-methoxy-5-methyl-naohthoic acid as the first building block for skeleton assembly of azinomycin B
