Help Finding Specific BlaZ Gene Type Sequences on Genbank
You might have already tried this, but how about doing a BLAST search using one of the sequences you do have, and perhaps limiting the organism to Staph a.
More info:
The below article did a similar comparison and mentions types RN9 and FAR10, perhaps these are related (or  misspelled originally)  See below.
&quot;Real-Time PCR Assay for Detection of blaZ Genes in Staphylococcus aureus Clinical Isolates&quot; at https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3993521/
mentions:
&quot;type A, PC1(pI254) and NCTC 9789; type B, 22260 and ST79/741; type C, 3804(pII3804), RN9(pII147), and V137; and type D, FAR10&quot;
In any case I highly recommend going to your original article of interest, and use the &quot;cited by&quot; function to find more recent papers.
