Fig. 1: In-cell 31P-NMR measurements of vacuolar polyP in yeast strains.

Chemical shifts of the terminal and central residues of vacuolar polyP are indicated, respectively. MDP was used as the std. reference. Wt indicates the wild-type BY4741 yeast strain. vtc2Δ, vtc3Δ, vtc2Δvtc3Δ, vtc1Δ, vtc4Δ indicates BY4741 yeast strain with deletion of vtc2, vtc3, vtc2 and vtc3, vtc1, vtc4 gene, respectively.
