Percentages of amino acid sequence identity of the putative NDH-2s from Synechocystis sp. strain PCC 6803 to known NDH-2 proteins from other organisms^a

Species	Identity (%) to:
	B. s.	E. c.	S. c.	Slr0851	Slr1743
Sll1484	18	27	24	27	33
Slr1743	17	30	27	32
Slr0851	16	29	28

^aSequence identities were determined with the FASTA program from the Genetics Computer Group package (5) at default settings. Abbreviations: B. s., Bacillus sp. strain YN-1; E. c., E. coli; S. c., Saccharomyces cerevisiae. Sll1484, Slr0851, and Slr1743 are the three putative NDH-2s from Synechocystis sp. strain PCC 6803.
