1 A preparation of malic enzyme was made from chicken liver. 2 The enzyme was incubated, in tritiated buffer containing NADP, with 2S, 3S-[2,3-2H2]malate. A third malate, 2S, 3R-[3-3H1]malate, was incubated with the enzyme, NADP, and unlabelled buffe

The enzymic synthesis of 6-farnesyl-5,7-dihydroxy-4-methylphthalide (4a) from 5,7-dihydroxy-4-methylphthalide (2) and (3RS)-mevalonic acid (1a) proceeds with inversion of configuration at C-5 in (1a).

A dialysed ammonium sulphate fraction of a cellfree preparation from Penicillium brevicompactum catalyses the synthesis of 6-farnesyl-5,7-dihydroxy-4-methylphthalide (10) from 5,7-dihydroxy-4-methylphthalide (1) and either (3RS)mevalonic acid (5) or

1. The enzyme trehalase was prepared from whole flesh flies, Sarcophaga barbata. 2. The rate of mutorotation of glucose released by the enzyme was compared with that of alpha-D-glucose, beta-D-glucose and an equimolar mixture of the two. 3. Derivativ

Mevalonic acid stereospecifically labelled with tritium in the 2-position was incubated, in a deuterium oxide medium containing adenosine triphosphate, with a soluble enzyme preparation from pig liver; and so converted into farnesyl pyrophosphate.
