CyanoLyase

RpcT family

Description

Gene name proposed by Six et al. (2007). This enzyme is not formerly biochemically characterized yet but indirect evidence suggests that it attaches a PEB at Cys-153 of beta-PC (Blot et al. 2009). RpcT is a paralog of CpcT and they are located in different positions of the PBS rod region of marine Synechococcus spp. (Six et al. 2007). Interestingly, RS9916 possesses both RpcT and CpcT.
