The core of the CCR4-NOT transcription factor complex. In Saccharomyces the CCR4-NOT core complex comprises Ccr4p, Caf1p, Not1p, Not2p, Not3p, Not4p, and Not5p.

Catalysis of the selective cleavage of Lys(or Arg)-Ile bond in complement subcomponent C1s to form the active form of C1s (EC:3.4.21.42).

The contractile element of skeletal and cardiac muscle; a long, highly organized bundle of actin, myosin, and other proteins that contracts by a sliding filament mechanism.

Catalysis of the cleavage of component C4 to C4a and C4b (Arg-Ala bond), and component C2 to C2a and C2b (Lys-Lys or Arg-Lys bond).

The repeating unit of a myofibril in a muscle cell, composed of an array of overlapping thick and thin filaments between two adjacent Z discs.

Catalysis of the cleavage of component factor B (Arg-Lys) when in complex with C3b or with cobra venom factor (CVF).

Platelike region of a muscle sarcomere to which the plus ends of actin filaments are attached.

Catalysis of the inactivation of complement subcomponents C3b, iC3b and C4b by proteolytic cleavage.

Catalysis of the preferential cleavage of Arg-Xaa, Lys-Xaa, but with more restricted specificity than trypsin.

Catalysis of the reaction: (5-L-glutamyl)-peptide + an amino acid = peptide + 5-L-glutamyl-amino acid.

Assembly of actin filaments by the addition of actin monomers to a filament.

Catalysis of the reaction: acyl-CoA + 1-acyl-sn-glycerol 3-phosphate = CoA + 1,2-diacyl-sn-glycerol 3-phosphate.

Disassembly of actin filaments by the removal of actin monomers from a filament.

Catalysis of the reaction: 1-pyrroline-5-carboxylate + NAD+ + H2O = L-glutamate + NADH + H+.

Catalysis of the reaction: UDP-glucose + 1,3-beta-D-glucosyl(n) = UDP + 1,3-beta-D-glucosyl(n+1).

Catalysis of the transfer of a segment of a 1,4-a-D-glucan chain to a primary hydroxyl group in a similar glucan chain.

Catalysis of the reaction: an 11-beta-hydroxysteroid + NADP+ = an 11-oxosteroid + NADPH + H+.

parallel actin filament bundle formation

Assembly of actin filament bundles in which the filaments are tightly packed (approximately 10-20 nm apart) and oriented with the same polarity.
