Effects of cyanide on rates and products of fatty acid synthesis by chloroplasts isolated from Spinacia oleracea
Journal Article
·
· Plant Physiol.; (United States)
Cyanide inhibited unesterified fatty acid synthesis but stimulated glyceride synthesis from (1-/sup 14/C) acetate when Spinacia oleracea chloroplasts were incubated in basal media. Both unesterified fatty acid and glyceride accumulation were inhibited when chloroplasts were incubated in a diacylglycerol mode. Stimulation of chloroplast fatty acid synthesis by either exogenous coenzyme A or Triton X-100 was almost completely abolished in the presence of cyanide. Stearoyl-ACP desaturation is considered to be inhibited to a greater extent than is fatty acid synthesis de novo.
