The effect of acid-or base-loading of spinach (Spinacia oleracea L.) leaf discs on the activation status of nitrate reductase (NR) in the dark and in the light was investigated. Activity of NR (NRA), measured in crude extracts of leaf discs with removed lower epidermis, which had been floating on Me

✦ Synopsis
The enzyme nitrite reductase (EC 1.6.6.4) is generally assayed in terms of disappearance of nitrite from the assay medium. We describe a technique which allowed estimation of the enzyme level in leaf tissues of Vigna mungo (L). Hepper in terms of the release of the product (NH3) of the enzyme reaction. The technique is offered as an alternative, possibly more convenient method for assay of nitrite reductase in plant tissue in vivo.

A specific enzyme method is described for the routine estimation of starch in small quantities (10-30 mg) of dried leaf tissue. A fl-glucanase-free preparation of amyloghicosidase is employed to hydrolyse starch to glucose; this is subsequently estimated by the glucose oxidase technique. The method
Smith±Lemli±Opitz syndrome (SLOS), an autosomal recessive condition with multiple malformations, mental retardation, and growth failure, results from markedly reduced activity of the ®nal enzyme in the cholesterol biosynthetic pathway, 7-dehydrocholesterol D 7 -reductase (DHCR7). We diagnosed SLOS i
