GC content, and CU of the 359 CDS of p42d. Red lines indicate the average in GC (58.1%) and CU (0.58). Blue lines indicate 1 standard deviation of GC ± 3.5% and CU ± 0.16. Highest and lowest percentage values of GC are 69.4 and 45.8 respectively. The CU limit values varies from 0.11 to 1.00. CDS distribution with the color codes for functional classes and the relevant regions described in Figure .
