Table 1 Comparison between RNase T₁ and RNase A 16S rRNA catalogs. See Supplementary Table for more details.

Enzyme	Attributes of the oligoribonucleotide catalog^†
	Length Range	Total Oligos	Distinct Oligos	Distinct Masses	Avg. Oligo Seqs per 16S	Avg. Masses per 16S
Without isotopes:
RNase T₁	1 – 54	898,494	8,601	858	128	77
RNase A	1 – 21	1,225,481	1,994	227	81	50
With isotopes (see Methods):
RNase T₁	1 – 54	898,494	8,601	2,404	128	159
RNase A	1 – 21	1,225,481	1,994	644	81	88

† The columns are:
Length Range: the minimum and maximum length of oligoribonucleotides in catalogs.
Total Oligos: the number of all oligoribonucleotides generated by complete RNase digestion.
Distinct Oligos: the number of different oligoribonucleotide sequences in the catalogs.
Distinct Masses: the number of different oligoribonucleotide masses in the catalogs.
Avg. Oligos per 16S: the average number of different oligoribonucleotide sequences generated by every 16S rRNA RNase digestion.
Avg. Masses per 16S: the average number of different oligoribonucleotide masses generated by every 16S rRNA RNase digestion.
