  2. Point accepted mutation - Wikipedia

    en.wikipedia.org/wiki/Point_accepted_mutation

    A PAM matrix is a matrix where each column and row represents one of the twenty standard amino acids. In bioinformatics, PAM matrices are sometimes used as substitution matrices to score sequence alignments for proteins. Each entry in a PAM matrix indicates the likelihood of the amino acid of that row being replaced with the amino acid of that ...

  3. Protospacer adjacent motif - Wikipedia

    en.wikipedia.org/wiki/Protospacer_adjacent_motif

    PAM and size of various CRISPR DNA nucleases . The canonical PAM is the sequence 5'-NGG-3', where "N" is any nucleobase followed by two guanine ("G") nucleobases. [9] Guide RNAs can transport Cas9 to any locus in the genome for gene editing, but no editing can occur at any site other than one at which Cas9 recognizes PAM.

  4. Allosteric modulator - Wikipedia

    en.wikipedia.org/wiki/Allosteric_modulator

    PAM-agonists work like PAMs, but also as agonists with and without the agonists they modulate. [4] PAM-antagonists work like PAMs, but also function as antagonists and lower the efficacy of the agonists they modulate. [4] negative allosteric modulators (NAM) lower agonist affinity and/or efficacy. [4] Maraviroc is a medicine that modulates CCR5.

  5. Privileged access management - Wikipedia

    en.wikipedia.org/wiki/Privileged_access_management

    Privileged Access Management (PAM) is a type of identity management and branch of cybersecurity that focuses on the control, monitoring, and protection of privileged accounts within an organization. Accounts with privileged status grant users enhanced permissions, making them prime targets for attackers due to their extensive access to vital ...

  6. Pathogen-associated molecular pattern - Wikipedia

    en.wikipedia.org/wiki/Pathogen-associated...

    Pathogen-associated molecular patterns (PAMPs) are small molecular motifs conserved within a class of microbes, but not present in the host. [1] They are recognized by toll-like receptors (TLRs) and other pattern recognition receptors (PRRs) in both plants and animals. [2]

  7. BLOSUM - Wikipedia

    en.wikipedia.org/wiki/BLOSUM

    In addition to BLOSUM matrices, a previously developed scoring matrix can be used. This is known as a PAM. The two result in the same scoring outcome, but use differing methodologies. BLOSUM looks directly at mutations in motifs of related sequences while PAM's extrapolate evolutionary information based on closely related sequences. [1]

    For example, Attorney General Pam Bondi issued a memo the day she was sworn in directing employees to end “illegal DEI” and “accessibility” discrimination.

  9. Substitution matrix - Wikipedia

    en.wikipedia.org/wiki/Substitution_matrix

    One PAM unit is defined as 1% of the amino acid positions that have been changed. To create a PAM1 substitution matrix, a group of very closely related sequences with mutation frequencies corresponding to one PAM unit is chosen. Based on collected mutational data from this group of sequences, a substitution matrix can be derived.
