Project Title:Comprehensive Nucleoside Analysis of Archaeal RNA Modification Profiles Reveals a m7G in the Conserved P-loop of 23S rRNA
Project Summary:Extremophilic archaea employ diverse chemical RNA modifications, providing a rich source of new enzymes for biotechnologically valuable RNA manipulations. Our understanding of the modified nucleoside profiles in Archaea, as well as the functions and dynamic regulation of specific RNA modifications is far from complete. Here, we established an extensive profile of nucleoside modifications in thermophilic and mesophilic Archaea through highly sensitive LC-MS/MS analysis and rigorous non-coding RNA depletion, identifying - with high confidence - at least four previously unannotated modifications in archaeal mRNAs. Nucleoside quantification analysis conducted on total, large, small, and mRNA-enriched subfractions of the model hyperthermophilic archaeon Thermococcus kodakarensis revealed a series of modifications whose abundance is dynamically responsive to growth temperatures, implying that specific RNA modifications are fitness relevant under specific growth conditions. To predict the RNA-modifying enzymes most likely to generate the new and dynamic RNA modifications, we leveraged a bioinformatics analysis of open-access databases to annotate likely functional domains of archaeal proteins. Putative enzyme activities were confirmed in vitro and in vivo by assessing the presence of the target RNA modification in genetic deletion strains of T. kodakarensis. Our approach led to the discovery of a methyltransferase-encoded gene responsible for m7G modification in the P-loop of 23S rRNA peptidyl transferase center and validates a novel and effective platform for discovering RNA-modifying enzymes through LC-MS/MS analysis that will accelerate efforts of the community towards uncovering the complex and dynamic roles of RNA modifications.

Collection:

Collection ID:CO003852
Collection Summary:T. kodakarensis strains were grown at 85C in anaerobic artificial sea water supplemented with yeast extract and tryptone to mid-exponential phase (Optical density ~0.3) before harvest. Sources of Thermococcus sp. AM4, Sulfolobus islandicus M16.4, Sulfolobus acidocaldarius, and Methanococcus maripaludis biomasses were contributed by C.S. Raman (University of Maryland), Rachel Whitaker (University of Illinois at Urbana-Champaign), Sonja-Verena Albers (University of Freiburg), and Barney Whitman (University of Georigia), respectively. Harvested archaeal cell pellets were resuspended in 10 mL of TRI reagent (Molecular Research Center, Inc., Cat #TR118). The resuspended cells were homogenized using a beads beater at 4.0 m/s for 20 seconds x 2 cycles (MP Biomedicals, FastPrep-24TM). Subsequently, the mixture was centrifuged at 14000 g for 5 minutes to precipitate any cell debris. Supernatants were collected post-centrifugation and treated with 50 μL of BAN reagent (Molecular Research Center, Inc., Cat #BN191) per mL of supernatant for aqueous-organic phase separation. RNA from the aqueous phase was isolated by isopropanol precipitation and subjected to DNase I treatment (NEB, Cat #M0303S) to remove genomic DNA contamination. To further purify the DNase I-treated RNA, an equal volume of acid phenol-chloroform with isoamyl alcohol (125:24:1, Thermo Fisher Scientific, Cat #AM9722) was added to the reaction and centrifuged at 21300 g for 2 minutes to separate the aqueous phase from the organic phase. The aqueous phase containing RNA was then precipitated with 1.5 volumes of isopropanol and 0.1 volume of sodium acetate (Sigma Aldrich, Cat #S7899) at –20°C overnight. Finally, the precipitated RNA pellets were washed with 75% ethanol and dissolved in nuclease-free water.
Sample Type:Ribonucleic acid

Treatment:

Treatment ID:TR003868
Treatment Summary:To remove rRNA and tRNA, total RNA was separated into large (> 200 nt) and small RNA (< 200 nt) fractions using the RNA Clean and Concentrator Kit (Zymo Research, Cat #R1017). Subsequently, 50 ug of the large RNA fraction were subjected to rRNA depletion using the NEBNext rRNA Depletion Kit (NEB, Cat #E7850X) with the following changes: The NEBNext rRNA depletion solutions provided in the kit were substituted for customized DNA probe mixtures (at 1 uM for each probe) fully complementary to rRNA sequences corresponding to each archaeal species; All volumes for the probe hybridization, RNase H and DNase I digestion reactions were scaled up by fivefold in 10 parallel reactions. Following the enzymatic treatment, the reactions were cleaned up using RNA Clean and Concentrator Kit (Zymo Research, Cat #R1017), the mRNA-enriched fractions were eluted in 10 uL water and combined.

Sample Preparation:

Sampleprep ID:SP003865
Sampleprep Summary:mRNA-enriched samples were digested to nucleosides at 37°C overnight using a Nucleoside Digestion Mix (NEB, Cat #M0649S). The digested RNAs were subsequently injected without prior purification on an Agilent 1290 Infinity II UHPLC equipped with a G7117 diode array detector and an Agilent 6495C Triple-Quadrupole Mass Spectrometer operating in positive electrospray ionization (+ESI) mode.
