This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Phytochromes comprise a principal family of red/far-red light sensors in plants. We will attempt structure determination of the GAF domain of a phototaxis regulator phytochrome (PixJ), comprising the domain which houses the chromophore - phycocyanobilin (or PVB?). The constructs photoconvert and is only ~20 kDa; we would like to also determine its Pb andf Pg forms upon blue/green light exposure.

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 光敏色素包括植物中的红光/远红光传感器的主要家族。我们将尝试测定趋光性调节剂光敏色素（PixJ）的GAF结构域的结构，该结构域包含发色团-藻蓝胆素（或PVB？）。该构建体光转化并且仅为~20 kDa;我们还想确定其在蓝/绿色光暴露后的Pb和f Pg形式。
