Extended Data Fig. 5. The Sha-CdnE01 cyclase also binds the cabRNA during Φ80α-vir infection.

Extended Data Fig. 5

(a) Alignment of porcine OAS1, D. erecta cGLR, and bacterial CdnE03s. Conserved residues are highlighted in blue. (b) Alignment of the N-terminal helix, PβCD and C-terminal domains CD-NTases from staphylococcal species, belonging to different families (in different colors). The conserved basic residues involved in cabRNA binding by Ssc-CdnE03 are highlighted in red. Accession numbers are: S. nepalensis WP_096808822.1; S. hominis WP_0494417910.1; S. epidermidis WP_020363757.1 (CdnB03); S. pseudintermedius WP_101458501.1; S. saprophyticus WP_041080732.1; S. argenteus WP_076688059.1; S. hominis WP_071561002.1; S. sp. EGD-HP3 WP_021459889.1; S. haemolyticus WP_037559004.1; S. equorum WP_071664859.1; S. vitulinus WP_016911376.1; S. epidermidis W23144 (Cd–E03) - EES35648.1; S. sp. HMSC077B09 WP_070485035.1; S. schleiferi WP_050329628.1; S. chromogenes WP_037576868.1. (c) Detection of phage propagation after spotting ten-fold dilutions of the lytic DNA phages, Φ80α-vir, ΦNM1γ6, ΦNM4γ4, and Φ12γ3 onto lawns of S. aureus RN4220 harboring a plasmid expressing an incomplete (Sha-CdnE01 alone) or intact Sha-CBASS operon. (d) Agarose gel electrophoresis of the input and output RNA obtained after incubation of Sha-CdnE01 with total RNA extracted from uninfected staphylococci (RN4220) or from cells infected with Φ80α-vir phage. Data are representative of three independent experiments.
