This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. Expression of enzymes involved in glycoprotein biosynthesis for structural analysis by NMR and X-ray crystallography is being optimized in mammalian and yeast cells. High yield expression has been accomplished in HEK293 and Pichia pastoris and labeling methods (13C-, 15N-, and 2H-) are being pursued for NMR-based structural studies.

这个子项目是许多利用资源的研究子项目之一 由NIH/NCRR资助的中心拨款提供。子项目的主要支持 子项目的主要研究者可能是由其他来源提供的， 包括其他NIH来源。 列出的子项目总成本可能 代表子项目使用的中心基础设施的估计数量， NCRR赠款不直接向子项目或子项目工作人员提供资金。 在哺乳动物和酵母细胞中，通过NMR和X射线晶体学进行结构分析的糖蛋白生物合成中涉及的酶的表达正在优化。已在HEK 293和巴斯德毕赤酵母中实现了高产表达，并且正在追求标记方法（13 C-、15 N-和2 H-）用于基于NMR的结构研究。
