摘要
另一个室的内容物在花粉和绒毡层中分离。在绒毡层中有下列酶参与苯丙素代谢:莽草脱氢酶;苯丙氨酸ammonialyase;肉桂酸4-羟化酶;SAM (s -腺苷蛋氨酸):咖啡酸3- o -甲基转移酶;羟基肉桂酸辅酶a连接酶;“黄烷酮合酶”;chalcone-flavanone异构酶;SAM: 3'，4'-二羟基类黄酮3'- o -甲基转移酶;O-glucosyltransferase。据推测，这些来自绒毡层的酶在苯丙素转移到小室后，在外皮腔或腔内催化其代谢的不同步骤。
The occurrence of enzymes involved in phenylpropanoid metabolism in the tapetum fraction of anthers.
The contents of another loculus were separated in a pollen and tapetum fraction. The following enzymes involved in phenylpropanoid metabolism were present in the tapetum fraction: shikimate dehydrogenase; phenylalanine ammonialyase; cinnamic acid 4-hydroxylase; SAM (S-adenosylmethionine): caffeate 3-O-methyltransferase; hydroxycinnamate: CoA ligase; "flavanone synthase"; chalcone-flavanone isomerase; SAM: 3',4'-dihydroxyflavonoid 3'-O-methyltransferase; O-glucosyltransferase. It is postulated, that these enzymes derived from the tapetum catalyze the different steps of phenylpropanoid metabolism at or in cavities of the exine after their transfer into the loculus.
