1H, 15N and 13C resonance assignments of translationally-controlled tumor protein from photosynthetic microalga Nannochloropsis oceanica

Translationally-controlled tumor protein (TCTP) is a eukaryote-conserved protein with crucial roles in cellular growth. It has also been proposed that plant TCTP has functions specific to plant, while no structure of TCTP from photosynthetic organism has been reported. Nannochloropsis is a photosynthetic microalga with high yield of lipid and high-value polyunsaturated fatty acid, which is promising for biodiesel production. Study of growth-related proteins may provide new clue for improving the yield of lipid. TCTP from Nannochloropsis oceanica shares low sequence identity with structure-known TCTPs. Here we reported the NMR resonance assignments of TCTP from N. oceanica for further structural and functional studies.
