COMMENT     Original source text: Saccharomyces cerevisiae (clone:  pAB40) DNA.
            Dr. Graeme A. Reid (ebmo21@castle.edinburgh.ac.uk) writes us about
            the possibility of a sequence error, a deletion of a c at position
            4617-4618 (cc->ccc), which would extend the coding region to
            position 5225 instead of 4683.   He made the following
            observations: This sequence is homologous to Shewanella
            putrefaciens flavocytochrome c (L04283) and other fumarate
            reductases. The present GenBank entry indicates that OSM1 encodes a
            protein of 301 residues.  Extremely close sequence similarity
            between OSM1 protein and flavocytochrome c beyond the end point was
            found in another reading frame.  It is possible that a sequencing
            error accounts for this observation, but it has not been checked
            experimentally as yet.       The putative signal sequence of the
            OSM1 protein does not fit the consensus at all well and there is no
            evidence to suggest that this is a membrane protein or enters the
            secretory pathway.  The proposed correction would restore the
            sequebnce QxHPTG that is well conserved throughout the Frd family.
            with the histidine in the sequence having been identified at the
            active site in E.coli frdA (Schryder et al., 1991). Wild-type yeast
            cells have two cytochrome c proteins, iso-1 and iso-2, encoded by
            the two distinct genetic loci cyc1 and cyc7, respectively.  The
            iso-1 cytochrome c protein is the predominant cellular cytochrome
            c, normally representing about 95% of the material of that kind.
            The cyc1-512 mutant has a 38 bp deletion in the 3' nontranslated
            region which prevents proper transcription termination.  Authors
            suggest that polyadenylation may be coupled to transcription
            termination in yeast.  They also report a consensus sequence from
            many yeast genes.
