CC   -!- FUNCTION: TRANSFER OF ELECTRONS FROM NADH TO THE RESPIRATORY
CC       CHAIN. THE IMMEDIATE ELECTRON ACCEPTOR FOR THE ENZYME IS BELIEVED
CC       TO BE UBIQUINONE.
CC   -!- CATALYTIC ACTIVITY: NADH + UBIQUINONE = NAD(+) + UBIQUINOL.
CC   -!- SUBUNIT: COMPLEX I IS COMPOSED OF ABOUT 40 DIFFERENT SUBUNITS.
CC   -!- SUBCELLULAR LOCATION: MITOCHONDRIAL INNER MEMBRANE; MATRIX SIDE.
CC   -!- CAUTION: THE RECONSTRUCTION OF THE SEQUENCE WAS HELPED BY TWO
CC       PARTIAL EST SEQUENCES (AA548676 AND N31341). THERE ARE PROBABLY
CC       SOME MORE ERRORS IN THE C-TERMINAL PART.
