T clan


The structure of CpcT of Nostoc sp. PCC7120 and its complex with phycocyanobilin was resolved at 1.95 and 2.50 Å resolution (Protein Data Bank ID: 4O4O), respectively. CpcT forms a dimer and adopts a calyx-shaped β-barrel fold (Zhou et al., 2014). The structure of the CpeT of the cyanophage P-HM1 was resolved at 1.8 Å (Protein Data Bank ID: 5HI8; Gasper et al., 2017).

CpcT family GTHECHR1104 XP_001713602.1 Guillardia theta CCMP2712 Cr-PE 545 n.a. Low protoscan score but best BLASTP match to the CpcT family. This cpcT-like gene was characterized by complementation of Synechocystis sp. PCC6803 cpcT (Bolte et al. 2008). However, since G. theta possesses PE (Cr-PE 545) not PC, the function of this gene (despite its closest similarity to cpcT than cpeT families) must likely be to attach a PEB at Cys-159 of beta-PE. 222 09-28-2012
