Evidence is presented that micronuclei of Tetrahymena thermophila contain significant amounts of two types of histone H3. One is indistinguishable from that found in macronuclei and the other is unique to micronuclei. The micronucleus-specific H3 has a slightly faster mobility than the common H3 in three different gel systems (both of these species were artifactually lost during procedures for histone preparation in previous studies). Both micronuclear H3s appear to contain a single cysteine residue and are present in sucrose gradient-purified nucleosomes. Acid extracts from micronuclei also contain three prominent high molecular weight proteins that also were lost during previous procedures. These proteins are present in extracts from oligomers but are not observed in extracts from mononucleosomes, suggesting that they may be associated with linker regions between nucleosomes.
