| ORF2 | 309 | 12 | L. lactis phage r1t ORF38a (77/47) |
| ORF3 | 378 | 14 | L. lactis phage r1t ORF39a (69/51) |
| pblA | 3,021 | 107 | L. lactis phage r1t ORF40a (62/52) and ORF42a (42/27) |
| ORF4 | 693 | 26 | No significant similarity |
| pblB | 3,186 | 121 | S. thermophilus phage 01205 ORF45 (48/33)b |
a
ORF37 through ORF42 of phage r1t are within a region encoding structural proteins.
b
The similarity to ORF45 is limited to the carboxy-terminal half of PblB.
