Bacteriophage T4 genes sp and 40 apparently are the same.
The bacteriophage T4 spackle gene, which maintains host membrane integrity, mapped at the same position as gene 40 (head morphogenesis). The cloned spackle gene complemented and cross-reactivated a gene 40 mutant. Like the spackle mutant, gene 40 mutants were defective in genetic exclusion. Apparently, genes spackle and 40 are the same gene.
