Better statistics with higher gap penalties

A second search of SwissPROT using CAR1_DICDI is shown below. The SSEARCH (Smith-Waterman) program was used with the BLOSUM50 matrix and gap penalties of -14 for the first residue in a gap and -2 for each additional residue. Now, the highest scoring non-G-protein-coupled receptor sequence has an expectation value of E()=0.4. As before, rhodopsin R and calcitonin/secretin C/S members are noted.

The best scores are:                               s-w Z-score E(43470)
