The conversion of 3-deoxyarabinoheptulosonate 7-phosphate to 3-dehydroquinate by sorghum seedling preparations
Partially purified preparations from etiolated sorghum seedlings catalyzed the conversion of DAHP to DHQ. The reaction catalysed by DHQ synthetase was stimulated by 0.1 μM to 0.1 mM NAD in the presence O-0.5 mM Co^2^+. NADH at 1 μM stimulated the reaction as much as 50% but became inhibitory at 100μ...

Partially purified preparations from etiolated sorghum seedlings catalyzed the conversion of DAHP to DHQ. The reaction catalysed by DHQ synthetase was stimulated by 0.1 μM to 0.1 mM NAD in the presence O-0.5 mM Co^2^+. NADH at 1 μM stimulated the reaction as much as 50% but became inhibitory at 100μM. Co^2^+ at 0.5mM stimulated enzyme activity 3-fold; Mg^2^+, Mn^2^+, Cu^2^+, and Zn^2^+ were not stimulatory. EDTA at 5 mM inhibited the reaction 95% but its effects were reversed by equal concentrations of Co^2^+. Phe, Tyr, Trp, t-cinnamate, several hydroxylated cinnamates, DHS, quinate, and shikimate at 0.3 mM failed to affect enzyme activity but slight inhibition occurred with DHQ and protocatechuic acid at 0.3 mM, inhibition being 14 % and 22 %, respectively. DHQ synthetase activity also was detected in spinach leaves and potato tuber tissue. Synthetase activity appeared to increase in response to injury of potato tuber and sweet potato root tissues. |

The reaction catalysed by DHQ synthetase was stimulated by 0.1 μM to 0.1 mM NAD in the presence O-0.5 mM Co^2^+. NADH at 1 μM stimulated the reaction as much as 50% but became inhibitory at 100μM. Co^2^+ at 0.5mM stimulated enzyme activity 3-fold; Mg^2^+, Mn^2^+, Cu^2^+, and Zn^2^+ were not stimulatory. EDTA at 5 mM inhibited the reaction 95% but its effects were reversed by equal concentrations of Co^2^+. Phe, Tyr, Trp, t-cinnamate, several hydroxylated cinnamates, DHS, quinate, and shikimate at 0.3 mM failed to affect enzyme activity but slight inhibition occurred with DHQ and protocatechuic acid at 0.3 mM, inhibition being 14 % and 22 %, respectively. DHQ synthetase activity also was detected in spinach leaves and potato tuber tissue. Synthetase activity appeared to increase in response to injury of potato tuber and sweet potato root tissues.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="f">Elsevier Journal Backfiles on ScienceDirect 1907 - 2002</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Saijo, R.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Kosuge, T.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">in</subfield><subfield code="t">Phytochemistry</subfield><subfield code="d">Amsterdam : Elsevier</subfield><subfield code="g">17(1978), 2, Seite 223-225</subfield><subfield code="w">(DE-627)NLEJ17552694X</subfield><subfield code="w">(DE-600)2000313-4</subfield><subfield code="x">0031-9422</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:17</subfield><subfield code="g">year:1978</subfield><subfield code="g">number:2</subfield><subfield code="g">pages:223-225</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">http://linkinghub.elsevier.com/retrieve/pii/S0031-9422(00)94150-5</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_H</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">ZDB-1-SDJ</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_NL_ARTICLE</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">17</subfield><subfield code="j">1978</subfield><subfield code="e">2</subfield><subfield code="h">223-225</subfield></datafield></record></collection>
