The chemical reactions involving spermine, a polybasic amine found in human sperm, in ribosomes and in some viruses, which is involved in nucleic acid packaging. Synthesis is regulated by ornithine decarboxylase which plays a key role in control of DNA replication.

The chemical reactions involving spermidine, N-(3-aminopropyl)-1,4-diaminobutane.

Interacting selectively with major histocompatibility complex molecules; a set of molecules displayed on cell surfaces that are responsible for lymphocyte recognition and antigen presentation.

Any process that modulates blood pressure.

The formation from simpler components of interleukin-1 beta.

negative regulation of centriole replication

Any process that stops, prevents or reduces the rate of centriole replication.

major histocompatibility complex class I ligand

Interacting selectively with major histocompatibility complex class I molecules; a set of molecules displayed on cell surfaces that are responsible for lymphocyte recognition and antigen presentation.

Functions to increase the rate of ATP hydrolysis.

major histocompatibility complex class II ligand

The specific activation or halting of processes within a cell so that its vital functions markedly cease, rather than simply deteriorating gradually over time, which culminates in cell death.

regulation of interleukin-1 beta biosynthesis

Any process that modulates the frequency, rate or extent of the formation from simpler components of interleukin-1 beta.

regulation of chromatin assembly or disassembly

Any process that modulates the frequency, rate or extent of chromatin assembly or disassembly.

Any process of gene inactivation (silencing) in which small RNAs trigger degradation of mRNA.

positive regulation of interleukin-1 beta biosynthesis

Any process that activates or increases the rate of the formation from simpler components of interleukin-1 beta.

Any process that modulates the frequency, rate or extent of the centrosome cycle, the processes of centrosome duplication and separation.

Interacting selectively with any part of a Gram-positive bacterial cell.
