[EX A]: nitric oxide synthase

[EX Q]:  Transcripts appear to be initiated from an upstream promoter , P1 , located in front of the tRNA ( met1 ) gene and from three internal promoters : P2 is located immediately in front of the tRNA ( met2 ) gene ; PL10 is near the beginning of the L1 - L10 intergenic space , and PL12 is at the end of the L10 gene sequence .
[EX A]: L10 gene sequence
