Abstract: Described is a new enzyme, 31-O-desmethyl-FK-506 O-methyltransferase (FKMT) and its N-terminal amino acid sequence. This enzyme can specifically and preferentially methylate the C-31 hydroxy group in 31-O-desmethyl FK-506/FR-900506 and other 31-O-desmethyl analogs of FK-506/FR-900506 and related compounds such as 31-O-desmethyl immunomycin type molecules, also designated FK-520 and FR-900520 by Fujisawa. The enzyme can be isolated from a FK-506 producing microorganism Streptomyces sp. (Merck Culture Collection No. MA 6858) ATCC No. 55098. Employing the enzyme in its active form, supplemented with Mg.sup.+2 ion, in the presence of the methyl donor, S-adenosyl methionine (SAM), derivatives of 31-O-desmethyl FK-506, 31-O-desmethyl FK-520 and related 31-O-desmethyl compounds may be prepared.

Abstract: A method for flow injection analysis of total inorganic phosphate contained in an aqueous system such a cooling tower or boiler is described which uses a reducing agent and preservative composition therefore as the carrier for the sample to be analyzed, thereby creating a facile process which permits conversion of the various polyphosphates to orthophosphate and development of the molybdenum blue complex color reaction at 60.degree.-95.degree. C. and under 2-10 psi. This method has less stringent pressure and temperature requirements than those employed heretofore, thus permitting the use of more reliable and economic devices for measuring total inorganic phosphate in the field.
